Product Overview

The AD7820KNZ is a high speed, microprocessor-compatible 8-bit 2µS sampling Analog-to-digital Converter (ADC) which uses a half-flash conversion technique to achieve a conversion time of 1.36µs. The half-flash technique consists of 31 comparators, a most significant 4-bit ADC and a least significant 4-bit ADC. The input to the converter is tracked and held by the input sampling circuitry, eliminating the need for an external sample-and-hold for signals with slew rates less than 100mV/µs. The part is designed for ease of microprocessor interface with the converter appearing as a memory location or I/O port without the need for external interfacing logic. All digital outputs use latched, 3-state output buffer circuitry to allow direct connection to a microprocessor data bus or system input port. A non-three state overflow output is also provided to allow cascading of devices to give higher resolution.
  • Built-in track-and-hold function
  • No missed codes
  • No user trims required
  • Ratiometric operation
  • No external clock
  • Extended temperature range operation
