Product Summary

The AD9238BST-65 is a dual, 3V, 12-bit, 20 MSPS/40 MSPS/65 MSPS analog-to-digital converter. It features dual high performance sample-and-hold amplifiers and an integrated voltage reference. The AD9238BST-65 uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy and guarantee no missing codes over the full operating temperature range at data rates up to 65 MSPS. The applications of the AD9238BST-65 include Ultrasound Equipment, IF Sampling in Communications Receivers, IS-95, CDMA One, IMT-2000, Battery-Powered Instruments, Hand-Held Scopemeters, Low Cost Digital Oscilloscopes.
