Product Summary
The ADS7832BP is a monolithic CMOS 12-bit analog-to-digital converter with internal sample/hold and fourchannel multiplexer. The ADS7832BP is designed and tested for full dynamic performance with input signals to 50 kHz. The 5V single-supply requirements and standard CS, RD, and WR control signals make the part easy to use in microprocessor applications. Conversion results are available in two bytes through an 8-bit three-state output bus. The ADS7832BP is available in a 28-pin plastic DIP and 28-lead PLCC, fully specified for operation over the industrial –40℃ to +85℃ temperature range.
