LTC1850 Datasheet 1.25Msps Sampling ADCs

Manufacturer: Linear Technology (now Analog Devices)

Overview

LTC1850/LTC1851 8-Channel, 10-Bit/12-Bit, 1.25Msps Sampling ADCs DESCRIPTIO The 10-bit LTC®1850 and 12-bit LTC1851 are complete 8-channel data acquisition systems.

They include a flexible 8-channel multiplexer, a 1.25Msps successive approximation analog-to-digital converter with sample-and-hold, an internal 2.5V reference and reference buffer amplifier, and a parallel output interface.

The multiplexer can be configured for single-ended or differential inputs, two gain ranges and unipolar or bipolar operation.
