AD9235BRUZ-40

The AD9235BRUZ-40 is a 12-bit, 40 MSPS analog-to-digital converter (ADC) from Analog Devices, part of the AD9235 family. It employs a pipelined architecture with a sample-and-hold amplifier (SHA) and on-chip voltage reference, providing 12-bit accuracy with no missing codes over the full operating temperature range. The ADC features a differential input with 500 MHz bandwidth and supports both differential and single-ended input types. Key electrical characteristics include a typical signal-to-noise ratio (SNR) of 70 dBc and spurious-free dynamic range (SFDR) of 85 dBc at Nyquist at 65 MSPS. The device consumes 300 mW typical power at 65 MSPS. The analog input voltage range is flexible from 1 V p-p to 2 V p-p. The data interface is parallel. The ADC operates from a single 3 V analog supply (2.7 V to 3.6 V) and a digital supply of 2.25 V to 3.6 V. The operating temperature range is -40°C to 85°C. The device is available in a 28-TSSOP (0.173", 4.40mm Width) surface-mount package. Typical applications include ultrasound equipment, IF sampling in communications receivers, battery-powered instruments, and low-cost digital oscilloscopes.
