General Description
ADS7808 General Description
The ADS7808 is a complete 12-bit sampling analogto- digital using state-of-the-art CMOS structures. It contains a 12-bit capacitor-based SAR A/D with S/H, reference, clock, and a serial data interface. Data can be output using the internal clock, or can be synchronized to an external data clock.
The ADS7808 also provides an output synchronization pulse for ease of use with standard DSP processors.
The ADS7808 is specified at a 100kHz sampling rate, and guaranteed over the full temperature range. Lasertrimmed scaling resistors provide various input ranges including ±10V and 0V to 5V, while an innovative design operates from a single +5V supply, with power dissipation under 100mW. The 20-pin ADS7808 is available in a plastic 0.3" DIP and in an SOIC, both fully specified for operation over the industrial 40°C to +85°C range.
