Description

The LTC®1609 is a 200ksps, serial sampling 16-bit A/Dconverter that draws only 65mW (typical) from a single 5Vsupply. This easy-to-use device includes a sample-and-hold, a precision reference, a switched capacitor succes-sive approximation A/D and trimmed internal clock.

The input range of LTC1609  is specified for bipolar inputs of ±10V,±5V and ±3.3V and unipolar inputs of 0V to 10V, 0V to 5Vand 0V to 4V. Maximum DC specs include 2LSB INL and16-bit no missing codes over temperature. It has a typicalsignal-to-noise ratio of 87dB.

The ADC has a high speed serial interface. The serialoutput data can be clocked out using either the internalserial shift clock or be clocked out by anexternal shiftclock. A separate convert start input (R/C) and a data readysignal (BUSY) ease connections to FIFOs, DSPs andmicroprocessors.
