DESCRIPTION
The AMC7820 is a complete analog monitoring and control
circuit that includes an 8-channel, 12-bit Analog-to-Digital
Converter (ADC), three 12-bit Digital-to-Analog Converters
(DACs), nine operational amplifiers, a thermistor current source,
an internal +2.5V reference, and an SPI
serial interface.
External reference may be applied. Typical power dissipation
is 40mW. For the ADC, the unbuffered analog input range is
0V to +5.0V, and the buffered analog common-mode input
range is 0V to +3.8V. For the DACs, the analog output range
is 0V to +2.5V or 0V to +5.0V.
The AMC7820 is ideal for multichannel applications where
low power and small size are critical. The AMC7820 is
available in a TQFP-48 package and is fully specified and
tested over the –40
°
C to +85
°
C temperature range.
SPI is a trademark of Motorola.
