Low Power Dissipation: 10mW Sample Rate: 100ksps Samples Inputs Beyond Nyquist, 72dB S/(N + D) and 82dB THD at fIN = 100kHz Single Supply 5V or ± 5V Operation Power Shutdown to 1µA in Sleep Mode 180µA Nap Mode (LTC1277) with Instant Wake-Up Internal Reference Can Be Overdriven Internal Synchronized Clock 0V to 4.096V or ± 2.048V Input Ranges (1mV/LSB) 24-Lead SO Package
The LTC ®1274/LTC1277 are 8µs 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 2µs sample-and-hold, a precision reference and an internally trimmed clock. Unipolar and bipolar conversion modes add to the flexibility of the ADCs.
