ADC0820

8-Bit High Speed µP Compatible A/D Converter with

Track/Hold Function

General Description

Features

n Built-in track-and-hold function

n No missing codes

By using

a half-flash conversion technique, the 8-bit

ADC0820 CMOS A/D offers a 1.5 µs conversion time and

dissipates only 75 mW of power. The half-flash technique

consists of 32 comparators, a most significant 4-bit ADC and

a least significant 4-bit ADC.

n No external clocking

n Single supply — 5 V_DC

n Easy interface to all microprocessors, or operates

stand-alone

n Latched TRI-STATE^®output

n Logic inputs and outputs meet both MOS and T²L

voltage level specifications

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 moving at less than 100 mV/µs.

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.

n Operates ratiometrically or with any reference value

equal to or less than V_CC

n 0V to 5V analog input voltage range with single 5V

supply

Key Specifications

n No zero or full-scale adjust required

n Overflow output available for cascading

n 0.3" standard width 20-pin DIP

n 20-pin molded chip carrier package

n 20-pin small outline package

n Resolution

8 Bits

2.5 µs Max (RD Mode)

1.5 µs Max (WR-RD Mode)

75 mW Max

n Conversion Time

n Low Power

n 20-pin shrink small outline package (SSOP)

n Total Unadjusted

⁄2 LSB and 1 LSB
