ADC0820
8-Bit, high-speed,
μ
P-compatible A/D converter
with track/hold function
568
August 31, 1994
853-1631 13721
DESCRIPTION
By using a half-flash conversion technique, the 8-bit ADC0820
CMOS A/D offers a 1.5
μ
s conversion time while dissipating a
maximum 75mW of power. 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 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/
μ
s.
For ease of interface to microprocessors, the ADC0820 has been
designed to appear as a memory location or I/O port without the
need for external interfacing logic.
FEATURES
