The AD7821KRZ is a LC²MOS high speed µP compatible 8-bit Analog-to-digital Converter (ADC) with track/hold functions. It offers a conversion time of 660ns and 100kHz signal bandwidth. The sampling instant is better defined and occurs on the falling edge of WR or RD. The provision of a VSS pin allows the part to operate from ±5V supplies and to digitize bipolar input signals. Alternatively, for uni-polar inputs, the VSS pin can be grounded and the converter will operate from a single +5V supply, like the AD7820. It has a built-in track-and-hold function capable of digitizing full-scale signals up to 100kHz maximum. It also uses a half-flash conversion technique that eliminates the need to generate a CLK signal for the ADC. It designed with standard microprocessor control signals and latched, 3-state data outputs capable of interfacing to high speed data buses. An overflow output (OFL) is also provided for cascading devices to achieve higher resolution.
