The AD7827 is a high speed, single channel, low power, analog-to- digital converter with a maximum throughput of 1 MSPS that operates from a single 3 V or 5 V supply. The AD7827 contains a track/hold amplifier, an on-chip 2.5 V reference (2% tolerance), a 420 ns 8-bit half-flash ADC and a serial interface. The serial interface is compatible with the serial interfaces of most DSPs (Digital Signal Processors). The throughput rate of the AD7827 is dependent on the clock speed of the DSP serial interface.
