Overview
LTC1274/LTC1277 12-Bit, 10mW, 100ksps ADCs with 1µ A Shutdown FEATURES s s s DESCRIPTIO s s s s s s s 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.
Two power-down modes are available in the LTC1277.
In Nap mode, the LTC1277 draws only 180µA and the instant wake-up from Nap mode allows the LTC1277 to be powered down even during brief inactive periods.
