LTC1274 - 12-Bit, 10mW, 100ksps ADCs With 1µA Shutdown

The LTC1274 LTC1277 are 8s sampling 12-bit A/D converters which draw only 2mA (typ) from single 5V or 5V supplies. These easy-to-use devices come complete with a 2ms sample-and-hold, a precision reference and an internally trimmed Clock Unipolar and bipolar conversion modes add to the flexibility of the ADCs
Two power-down modes are available in the LTC1277. In Napmode, the LTC1277 draws only 180A and the instant wake-up from Nap mode allows the LTC1277 to be powered down even during brief inactive periods. In Sleep mode only 1A will be drawn. A REFRDY signal is used to show the ADC is ready to sample after waking up from Sleep mode. The LTC1274 also provides the Sleep mode and REFRDY signal.
The A/D converters convert 0V to 4.096V unipolar inputs from a single 5V supply or 2.048V bipolar inputs from 5V supplies.
The LTC1274 has a single-ended input and a 12-bit parallel data format. The LTC1277 offers a differential input and a 2-byte read format. The bipolar mode is formatted as 2s complement for the LTC1274 and offset binary for the LTC1277.
