Features

LTC2389-16

16-Bit, 2.5Msps SAR ADC

with Pin-Configurable Analog

Input Range and 96dB SNR

Description

The LTC

2389-16 is a low noise, high speed 16-bit

successive approximation register (SAR) ADC. Operating

from a single 5V supply, the LTC2389-16 supports pin-

configurable fully differential (±4.096V), pseudo-differ-

ential unipolar (0V to 4.096V), and pseudo-differential

bipolar (±2.048V) analog input ranges, allowing it to

interface with multiple signal chain formats without re-

quiring additional level translation or signal conditioning.

The LTC2389-16 achieves ±1LSB INL (maximum), no

missing codes at 16-bits, and 96.0dB (fully differential)/

93.5dB (pseudo differential) SNR (typical).

The LTC2389-16 includes a precision internal 4.096V

reference, with a guaranteed 0.5% initial accuracy and a

±20ppm/°C (maximum) temperature coefficient, as well

as an internal reference buffer. Fast 2.5Msps throughput

with no cycle latency in the parallel interface modes

makes the LTC2389-16 ideally suited for a wide variety

of high speed applications. An internal oscillator sets

the conversion time, easing external timing considera-

tions. The LTC2389-16 dissipates only 162.5mW at

2.5Msps, while both nap and sleep power-down modes

are provided to further reduce power consumption during

inactive periods.
