AD9432BSVZ-105

The AD9432BSVZ-105 is a 12-bit monolithic sampling analog-to-digital converter (ADC) with an on-chip track-and-hold circuit, optimized for high-speed conversion. It operates up to a 105 MSPS conversion rate with outstanding dynamic performance over its full operating range. The ADC requires only a single 5.0 V power supply and a 105 MHz encode clock for full performance operation. No external reference or driver components are required for many applications.

Key specifications include 12-bit resolution, 105 MSPS sampling rate, differential input with 2 V p-p range, pipelined architecture, parallel data interface, 500 MHz analog bandwidth, typical SNR of 67 dB at 49 MHz input, typical SFDR of 80 dBc at 49 MHz input, and power dissipation of 850 mW typical at 105 MSPS. The digital outputs are TTL-/CMOS-compatible with a separate output power supply pin supporting 3.3 V logic. Output format is twos complement.

The device is available in a surface-mount 52-TQFP exposed pad package (10x10 mm) and operates over the industrial temperature range of -40°C to 85°C. The analog supply voltage is 5 V, and the digital supply voltage range is 2.7 V to 3.6 V.

Typical applications include communications base stations, wireless local loop (WLL), local multipoint distribution service (LMDS), HDTV broadcast cameras, and film scanners.
