Product specification

ADC0820

8-Bit, high-speed,

µP-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

µs 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/

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.

FEATURES

• Built-in track-and-hold function

• No missing codes

• No external clocking

• Single supply—5V

DC

• Easy interface to all microprocessors, or operates stand-alone

• Latched 3-State outputs

• Logic inputs and outputs meet both MOS and TTL voltage level

specifications

• Operates ratiometrically or with any reference value equal to or

less than VDD

• 0V to 5V analog input voltage range with single 5V supply

• No zero- or full-scale adjust required

• Overflow output available for cascading

• 0.3″ standard width 20-pin DIP
