AD9235 is a 12-bit, 20/40/65 MSPS 3 V A/D converter with single 3 V supply operation (2.7 V to 3.6 V), SNR = 70 dBc to Nyquist at 65 MSPS, SFDR = 85 dBc to Nyquist at 65 MSPS, low power (300 mW at 65 MSPS), differential input with 500 MHz bandwidth, on-chip reference and SHA, DNL = ±0.4 LSB, flexible analog input (1 V p-p to 2 V p-p range), offset binary or twos complement data format, clock duty cycle stabilizer etc.
The AD9235 is a 12‑bit, 20/40/65 MSPS analog‑to‑digital converter that operates from a single 3 V supply and includes a high‑performance sample‑and‑hold amplifier and on‑chip reference. It offers low power consumption (300 mW at 65 MSPS), differential inputs with up to 500 MHz bandwidth, and selectable output data formats.
Typical applications include ultrasound equipment, communications receivers, battery‑powered instruments, hand‑held oscilloscopes, and low‑cost digital oscilloscopes. The device is offered in 28‑lead TSSOP and 32‑lead LFCSP packages and is qualified for industrial temperature ranges (-40 °C to +85 °C).
