The LTC

®1609 is a 200ksps, serial sampling 16-bit A/D

converter that draws only 65mW (typical) from a single 5V

supply. 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 is specified for bipolar inputs of

±10V,

±5V and ±3.3V and unipolar inputs of 0V to 10V, 0V to 5V

and 0V to 4V. Maximum DC specs include

±2LSB INL and

16-bit no missing codes over temperature. It has a typical

signal-to-noise ratio of 87dB.

The ADC has a high speed serial interface. The serial

output data can be clocked out using either the internal

serial shift clock or be clocked out by an external shift

clock. A separate convert start input (R/C) and a data ready

signal (BUSY) ease connections to FIFOs, DSPs and

microprocessors.
