ADC0820 Datasheet | NXP Semiconductors

Philips Semiconductors Linear Products Product specification 8-Bit, high-speed, µP-patible A/D converter with track/hold function DESCRIPTION By using a half-flash conversion technique, the 8-bit ADC0820 CMOS A/D offers a 1.5µs conversion time while dissipating a maximum 75mW of power. The half-flash technique consists of 31 parators, a most significant 4-bit ADC and a least significant 4-bit ADC. The input to the ADC0820 is tracked and held by the input sampling circuitry, eliminating the need for an external sample-and-hold for signals slewing at less than 100mV/µs. For ease of interface to microprocessors, the ADC0820 has been designed to appear as a memory location or...
