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.
