General Description

The DLVR Series Mini Digital Output Sensor is based on All Sensors’ CoBeam

2 TM

Technology. This reduces package stress

susceptibility, resulting in improved overall long term stability. The technology also vastly improves position sensitivity

compared to single die devices.

The supply voltage options ease integration of the sensors into a wide range of process control and measurement sys-

tems, allowing direct connection to serial communications channels. For battery-powered systems, the sensors can enter

very low-power modes between readings to minimize load on the power supply.

These calibrated and compensated sensors provide accurate, stable output over a wide temperature range. This series

is intended for use with non-corrosive, non-ionic working fluids such as air, dry gases and the like. A protective parylene

coating is optionally available for moisture/harsh media protection.

Device Options

The following is a list of factory programmable options. Consult the factory to learn more about the options.

Interface

I2C and SPI interfaces are available. NOTE: SPI interface is only available with eight (8) lead packages.

Supply Voltage

Devices are characterized at either 3.3V or 5.0V depending on the options selected. It is suggested to select

the option that most closely matches the application supply voltage for best possible performance.

Speed/Power

There are four options of Speed/Power. These are Fast(F), Noise Reduced(N), Low Power(L) and Sleep mode(S).

Fast Mode(F) Is the fastest operating mode where the device operates with continuous sampling at the

fastest internal speed.

Noise Reduced(N): Also operates with continuous samples however the ADC is set for over sampling

for noise reduction. The conversion times are resultantly longer than the Fast(F) mode however, there is

approximately 1/2 bit reduction in noise.

Low Power(L): Is similar to the Fast(F) mode with exception that the device uses an internal timer to

delay between pressure conversions. The internal timer time-out triggers the next conversion cycle. The

update rate is commensurately lower for this mode as a result.

Sleep(S): Is similar to the Low Power(L) mode however the trigger to initiate a sample comes from the

user instead of an internal timer. This is ideal for very low update rate applications that requirelow

power usage. It is also ideal for synchronizing the data conversions with the host microprocessor.

Coating

Parylene Coating: Parylene coating provides a moisture barrier and protection form some harsh media. Con-

sult factory for applicability of Parylene for the target application and sensor type. This option is not available

for pressure ranges below 10 inH2O.

Operation Overview

The DLVR is a digital sensor with a signal path that includes a sensing element, a 14 bit analog to digital con-

verter, a DSP and an IO block that supports either an I2C or SPI interface (see Figure 1 below). The sensor also

includes an internal temperature reference and associated control logic to support the configured operating mode.

The sensing element is powered down while not being sampled to conserve power. Since there is a single ADC,

there is also a multiplexer at the front end of the ADC that selects the signal source for the ADC.

The DSP receives the converted pressure and temperature information and applies a multi-order transfer function

to compensate the pressure output. This transfer function includes compensation for span, offset, temperature ef-

fects on span, temperature effects on offset and second order temperature effects on both span and offset. There is

also linearity compensation for gage devices and front to back linearity compensation for differential devices.

There are two effective operating modes of the sensor 1) Free Running and 2) Triggered. The control logic performs

the synchronization of the internal functions according the factory programmed Power/Speed option (see Table

1). The Control Logic also determines the Delay between ADC samples, the regularity of the Special cycles and

whether or not the ADC performs the Over Sampling. Refer to Figure 2 for the communication model associated

with the operating modes listed below.

Free Running Mode: In the free running mode, conversion cycles are initiated internally at regular intervals.

There are three options available that operate in the Free Running mode (F, N and L). Two of these (F and N)

run continuously while the third option (L) has an approximate 6 ms delay between conversion cycles. All

three options have Special cycles inserted at regular intervals to accomplish the ADC zeroing and temperature

measurements. Two of the options utilize oversampling. Refer to Table 1 for specific option controls.

Triggered Mode: In the Triggered Mode, a conversion cycle is initiated by the user (or host uP). There are two

available methods to wake the sensor from sleep mode. The first method (Wake All) is to wake the sensor and

perform all three measurement cycles (Z, T and P). This provides completely fresh data from the sensor. The

second method (Wake P) is to wake the sensor from sleep and only perform the pressure measurement (P).

When using this second method, it is up to the user to interleave Wake All commands at regular intervals to

ensure there is sufficiently up to date temperature information. Also, the Wake Pressure method is only avail-

able from the I2C interface (not available using a SPI interface).

The ADC performs conversions on the raw sensor signal (P), the temperature reference (T) and a zero reference (Z)

during an ADC zero cycle. It also has an oversampling mode for a noise reduced output. A conversion cycle that is

measuring pressure is called a Normal cycle. A cycle where either a temperature measurement or zeroing is being

performed is called a Special cycle.
