AD AD7820KR High Speed 8-Bit ADC SOIC20 SMD

Manufactured by Analog Devices - AD7820KR - SOIC20 SMD Package

LC²MOS High Speed µP-Compatible 8-Bit ADC

The AD7820 is a high speed, microprocessor compatible 8-bit analog-to-digital converter which uses a half-flash conversion technique to acheive a conversion time of 1.36µs. The converter has a 0V to +5V analog input voltage range with a single +5V supply.

The half-flash technique consists of 21 comparators, a most significant 4-bit ADC and a least significant 4-bit ADC. The input to the AD7820 is tracked and held by the sampling circuitry, eliminating the need for an external sample and hold for signals with slew rates less than 100mV/↨0s.
