ADC78H89
7-Channel, 500 KSPS, 12-Bit A/D Converter
General Description
The ADC78H89 is a low-power, seven-channel CMOS 12-bit
analog-to-digital converter with a conversion throughput of
500 KSPS. The converter is based on a successive-
approximation register architecture with an internal track-
and-hold circuit. It can be configured to accept up to seven
input signals on pins AIN1 through AIN7.
The output serial data is straight binary, and is compatible
with several standards, such as SPI
, QSPI
, MICROW-
IRE
, and many common DSP serial interfaces.
The ADC78H89 may be operated with independent analog
and digital supplies. The analog supply (AV
DD
) can range
from +2.7V to +5.25V, and the digital supply (DV
DD
) can
range from +2.7V toAV
DD
. Normal power consumption using
a +3V or +5V supply is 1.5 mW and 8.3 mW, respectively.
The power-down feature reduces the power consumption to
just 0.3 μW using a +3V supply, or 0.5 μW using a +5V
supply. The ADC78H89 is packaged in a 16-lead TSSOP
package. Operation over the industrial temperature range of
40C to +85C is guaranteed.
