LTC2314-14

14-Bit, 4.5Msps Serial

Sampling ADC in TSOT

FEATURES

DESCRIPTION

The

LTC

2314-14

is a 14-bit, 4.5Msps, serial sampling A/D

converter that draws only 6.2mA from a wide range analog

supply adjustable from 2.7V to 5.25V. The LTC2314-14

contains an integrated bandgap and reference buffer which

provide a low cost, high performance (20ppm/°C max)

and space saving applications solution. The LTC2314-14

achieves outstanding AC performance of 77dB SINAD and

–85dB THD while sampling a 500kHz input frequency.

The extremely high sample rate-to-power ratio makes the

LTC2314-14 ideal for compact, low power, high speed

systems. The LTC2314-14 also provides both nap and

sleep modes for further optimization of the device power

within a system.

The LTC2314-14 has a high-speed SPI-compatible serial

interface that supports 1.8V, 2.5V, 3V and 5V logic. The

fast 4.5Msps throughput makes the LTC2314-14 ideally

suited for a wide variety of high speed applications.
