AD9235BRUZ-65

The AD9235BRUZ-65 is a 12-bit, 65 MSPS analog-to-digital converter (ADC) from Analog Devices. It uses a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at data rates up to 65 MSPS. The device operates from a single 3 V supply (2.25 V to 3.6 V) and features a sample-and-hold amplifier (SHA) and on-chip voltage reference.

Key electrical specifications include a typical signal-to-noise ratio (SNR) of 70 dBc and a spurious-free dynamic range (SFDR) of 85 dBc, both measured to Nyquist at 65 MSPS. The ADC supports both differential and single-ended input types with an analog input voltage range of 1 V p-p to 2 V p-p. It also provides a parallel data interface and supports both external and internal reference types.

The device is designed for low power consumption, dissipating only 300 mW at 65 MSPS. It operates over a temperature range of -40°C to +85°C and is available in a 28-TSSOP surface-mount package. The pipelined architecture and high dynamic performance make it suitable for applications such as ultrasound equipment, IF sampling in communications receivers, and battery-powered instruments.
