*NO SCALING ON AD7890-2
Power dissipation in normal mode is low at 30 mW typ and the
part can be placed in a standby (power-down) mode if it is not
required to perform conversions. T he AD7890 is fabricated in
Analog Devices’ Linear Compatible CMOS (LC
2
MOS) process,
a mixed technology process that combines precision bipolar cir-
cuits with low power CMOS logic. T he part is available in a
24-pin, 0.3" wide, plastic or hermetic dual-in-line package or in
a 24-pin small outline package (SOIC).
PRODUCT HIGHLIGHT S
1. Complete 12-Bit Data Acquisition System on a Chip
T he AD7890 is a complete monolithic ADC combining an
eight-channel multiplexer, 12-bit ADC, +2.5 V reference and
a track/hold amplifier on a single chip.
2. Separate Access to Multiplexer and ADC
T he AD7890 provides access to the output of the multiplexer
allowing one antialiasing filter for eight channels—a consid-
erable saving over the eight antialiasing filters required if the
multiplexer was internally connected to the ADC.
3. High Speed Serial Interface
T he part provides a high speed serial interface for easy
connection to serial ports of microcontrollers and DSP
processors.

T he AD7890 is an eight-channel 12-bit data acquisition system.
T he part contains an input multiplexer, an on-chip track/hold
amplifier, a high-speed 12-bit ADC, a +2.5 V reference and a high
speed, serial interface. T he part operates from a single +5 V supply
and accepts an analog input range of
±
10 V (AD7890-10), 0 V to
+4.096 V (AD7890-4) and 0 V to +2.5 V (AD7890-2).
T he multiplexer on the part is independently accessible. T his
allows the user to insert an antialiasing filter or signal condition-
ing, if required, between the multiplexer and the ADC. T his
means that one antialiasing filter can be used for all eight chan-
nels. Connection of an external capacitor allows the user to
adjust the time given to the multiplexer settling to include any
external delays in the filter or signal conditioning circuitry.
Output data from the AD7890 is provided via a high speed bidi-
rectional serial interface port. T he part contains an on-chip con-
trol register, allowing control of channel selection, conversion
start and power-down via the serial port. Versatile, high speed
logic ensures easy interfacing to serial ports on microcontrollers
and digital signal processors.
In addition to the traditional dc accuracy specifications such as
linearity, full-scale and offset errors, the AD7890 is also speci-
fied for dynamic performance parameters including harmonic
distortion and signal-to-noise ratio.
