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. |
