Description

The LTC 1606 is a 250ksps, sampling 16-bit A/D con-verter that draws only 75mW (typical) from a single 5V supply.This easy-to-use device includes sample-and-hold, precision reference, switched capacitor successive approximation A/D and trimmed internal clock.
The LTC1606's input range is an industry standard 10V. Maximum DC specs include 2.0LSB INL and 16 bits no missing codes over temperature. An external reference can be used if greater accuracy over temperature is needed.
The 90dB signal-to-noise ratio offers an improvement of 3dB over competing devices, and the RMS transition noise
is reduced (0.65LSB vs 1LSB) relative to competitive parts.
The ADC has a microprocessor compatible, 16-bit or two byte parallel output port. A convert start input and a data
ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors.
