The LTC1292 and LTC1297 are 12‑bit successive‑approximation A/D converters with differential inputs, built‑in sample‑and‑hold and a three‑wire serial interface. The LTC1292 operates at up to 60 kHz throughput, while the LTC1297 includes an automatic power‑down mode for ultra‑low standby current.
The document lists key specifications such as resolution, supply current, voltage ranges, and absolute maximum ratings, and includes pin descriptions, package options (8‑lead ceramic and plastic DIP), typical performance curves, and application notes for temperature monitoring and other sensor interfaces.
| Resolution | 12 Bits |
|---|---|
| Maximum Throughput Rate (LTC1292) | 60 kHz |
| Low Supply Current | 6.0 mA |
| Shutdown Supply Current (LTC1297) | 5 µA |
| Supply Voltage (VCC) to GND | 12 V |
| Operating Temperature Range | 0 °C to 70 °C (typical) / –40 °C to 85 °C (extended) |
The LTC1292 can digitize signals at up to 60 kHz.
In shutdown mode the LTC1297 draws about 5 µA supply current.
