OMNIBUS I/O Modules > AD40

Overview

The AD40 module features two, independent, very-high-speed analog input channels making it ideal for high-speed data acquisition and transient capture systems. Each channel employs Analog Devices’ AD9224 monolithic, single supply 12-bit, 40 MSPS analog to digital converter with an on-chip, high performance sample-and-hold amplifier and voltage reference. The A/D uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at up to 40 MHz data rates, and guarantees no missing codes over the full operating temperature range. A single clock input is used to control all internal conversion cycles. An out-of-range signal indicates an overflow condition which can be used with the most significant bit to determine low or high overflow. On-board circuitry adds gain/offset error adjustments for each channel to insure accurate measurements.
