PRODUCT DE SCRIPT ION
T he AD1876 is a 16-bit serial output sampling A/D converter
which uses a switched capacitor/charge redistribution architecture
to achieve a 100 kSPS conversion rate (10
μ
s total conversion
time). Overall performance is optimized by digitally correcting
internal nonlinearities through on-chip autocalibration.
T he circuitry of the AD1876 is partitioned onto two monolithic
chips, a digital control chip fabricated with Analog Devices’
DSP CMOS process and an analog ADC chip fabricated with
the BiMOS II process. Both chips are contained in a single
package.
T he serial output interface requires an external clock and
sample command signal. T he output data rate may be as high
as 2.08 MHz, and is controlled by the external clock. T he twos
complement format of the output data is MSB first and is di-
rectly compatible with the NPC SM5805 digital decimation fil-
ter used in consumer audio products. T he AD1876 is also
compatible with a variety of DSP processors.
T he AD1876 is packaged in a space saving 16-pin plastic DIP
and operates from +5 V and
±
12 V supplies; typical power con-
sumption is 235 mW. T he digital supply (V
DD
) is isolated from
the linear supplies (V
EE
and V
CC
) for reduced digital crosstalk.
Separate analog and digital grounds are also provided.
