LTC2389-16

16-Bit, 2.5Msps SAR ADC

with Pin-Configurable Analog

Input Range and 96dB SNR

Features

Description

The LTC^®2389-16 is a low noise, high speed 16-bit

successiveapproximationregister(SAR)ADC. Operating

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

configurable fully differential (±±.ꢀ96V), pseudo-differ-

ential unipolar (ꢀV to ±.ꢀ96V), and pseudo-differential

bipolar (±2.ꢀ±8V) 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.ꢀdB (fully differential)/

93.5dB (pseudo differential) SNR (typical).

Guaranteed Operation to 125ꢁC

The LTC2389-16 includes a precision internal ±.ꢀ96V

reference, with a guaranteed ꢀ.5% initial accuracy and a

±2ꢀppm/ꢁ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

areprovidedtofurtherreducepowerconsumptionduring

inactive periods.
