STANDBY
The AD7892 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. It is available in a 24-lead, 0.3" wide, plastic or hermetic
DIP or in a 24-lead SOIC.
PRODUCT HIGHLIGHTS
1. The AD7892-3 features a conversion time of 1.47
μ
s and a
track/hold acquisition time of 200 ns. This allows a through-
put rate for the part up to 600 kSPS. The AD7892-1 and
AD7892-2 operate with throughput rates of 500 kSPS.
2. The AD7892 operates from a single +5 V supply and con-
sumes 60 mW typ making it ideal for low power and portable
applications.
3. The part offers a high speed, flexible interface arrangement
with parallel and serial interfaces for easy connection to
microprocessors, microcontrollers and digital signal
processors.
GENERAL DESCRIPTION
The AD7892 is a high speed, low power, 12-bit A/D converter
that operates from a single +5 V supply. The part contains a
1.47
μ
s successive approximation ADC, an on-chip track/hold
amplifier, an internal +2.5 V reference and on-chip versatile
interface structures that allow both serial and parallel connec-
tion to a microprocessor. The part accepts an analog input range
of
±
10 V or
±
5 V (AD7892-1), 0 V to +2.5 V (AD7892-2) and
±
2.5 V (AD7892-3). Overvoltage protection on the analog inputs
for the AD7892-1 and AD7892-3 allows the input voltage to go
to
±
17 V or
±
7 V respectively without damaging the ports.
The AD7892 offers a choice of two data output formats: a
single, parallel, 12-bit word or serial data. Fast bus access times
and standard control inputs ensure easy parallel interface to
microprocessors and digital signal processors. A high speed
serial interface allows direct connection to the serial ports of
microcontrollers and digital signal processors.
In addition to the traditional dc accuracy specifications such as
linearity, full-scale and offset errors, the part is also specified for
dynamic performance parameters including harmonic distortion
and signal-to-noise ratio.
