AD9233BCPZ-105

The AD9233BCPZ-105 is a 12-bit analog-to-digital converter (ADC) from Analog Devices, designed for high-speed data acquisition applications. It operates with a maximum sampling rate of 105 MSPS and uses a pipelined architecture with internal voltage reference and sample-and-hold amplifier. The ADC accepts either differential or single-ended analog inputs, and the wide-bandwidth input stage provides 650 MHz analog input bandwidth.

The device operates from a 1.8 V analog supply, while the digital output supply can range from 1.8 V to 3.3 V, making it suitable for interfacing with various logic families. It features a parallel data interface and supports offset binary, Gray code, or twos complement output formats. Typical dynamic performance includes a signal-to-noise ratio of 69.5 dBc (70.5 dBFS) and spurious-free dynamic range of 85 dBc at 70 MHz input. DNL is typically ±0.15 LSB.

The ADC is housed in a 48-VFQFN exposed pad package (48-LFCSP-VQ, 7x7 mm) and is intended for surface-mount assembly. It operates over the industrial temperature range of -40°C to +85°C. Applications include ultrasound equipment, IF sampling in communications receivers, battery-powered instruments, and low-cost digital oscilloscopes.
