LTC1850 - 8-Channel, 10-Bit/12-Bit, 1.25Msps Sampling ADCs - Linear Technology(凌力尔特)

功能描述

The 10-bit LTC1850 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.

The ADCs have a scan mode that will repeatedly cycle through all 8 multiplexer channels and can also be programmed with a sequence of up to 16 addresses and configurations that can be scanned in succession. The sequence memory can also be read back. The reference and buffer amplifier provide pin strappable ranges of 4.096V, 2.5V and 2.048V. The parallel output includes the 10-bit or 12-bit conversion result plus the 4-bit multiplexer address. The digital outputs are powered from a separate supply allowing for easy interface to 3V digital logic. Typical power consumption is 40mW at 1.25Msps from a single 5V supply.
