GENERAL DESCRIPTION
The AD7893 is a fast, 12-bit ADC that operates from a single
+5 V supply and is housed in a small 8-pin mini-DIP and 8-pin
SOIC. The part contains a 6
μ
s successive approximation A/D
converter, an on-chip track/hold amplifier, an on-chip clock and
a high speed serial interface.
Output data from the AD7893 is provided via a high speed,
serial interface port. This two-wire serial interface has a serial
clock input and a serial data output with the external serial clock
accessing the serial data from the part.
In addition to traditional dc accuracy specifications such as lin-
earity, full-scale and offset errors, the AD7893 is also specified
for dynamic performance parameters, including harmonic dis-
tortion and signal-to-noise ratio.
The part accepts an analog input range of
±
10 V (AD7893-10),
±
2.5 V (AD7893-3), 0 V to +5 V (AD7893-5) or 0 V to +2.5 V
(AD7893-2) and operates from a single +5 V supply, consuming
only 25 mW typical.
The AD7893 is fabricated in Analog Devices’ Linear Compat-
ible CMOS (LC
2
MOS) process, a mixed technology process
that combines precision bipolar circuits with low power CMOS
logic. The part is available in a small, 8-pin, 0.3" wide, plastic or
hermetic dual-in-line package (mini-DIP) and in an 8-pin, small
outline IC (SOIC).

PRODUCT HIGHLIGHTS
1. Fast, 12-Bit ADC in 8-Pin Package
The AD7893 contains a 6
μ
s ADC, a track/hold amplifier,
control logic and a high speed serial interface, all in an 8-pin
package. This offers considerable space saving over alterna-
tive solutions.
2. Low Power, Single Supply Operation
The AD7893 operates from a single +5 V supply and con-
sumes only 25 mW. This low power, single supply operation
makes it ideal for battery powered or portable applications.
3. High Speed Serial Interface
The part provides high speed serial data and serial clock lines,
allowing for an easy, two-wire serial interface arrangement.
