Product Summary
The AD9235BRU-40 is a monolithic, single 3 V supply, 12-bit, 20/40/65 MSPS analog-to-digital converter. It features a high performance sample-and-hold amplifier (SHA) and voltage reference. The AD9235BRU-40 uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 20/40/65 MSPS data rates and guarantee no missing codes over the full operating temperature range. The applications of the AD9235BRU-40 include Ultrasound Equipment, IF Sampling in Communications Receivers, Battery-Powered Instruments, Hand-Held Scopemeters, Low Cost Digital Oscilloscopes.
