MB88146A General Description
MB88146A Features
•Ultra low power consumption (1.2 mW/chl: typical)
•Ultra compact package
•Built-in 12-channel R-2R type 8-bit D/A converter
•Built-in 12-bit I/O expander (8 bits also function as analog output)
•Built-in analog output amplifier (sink current 1.0 mA maximum, source current 1.0 mA maximum)
•Built-in power-on detection circuit (initialized at detection of VccD power-on)
•MCU interface compatible with 3 V to 5 V systems
•Power divided into MCU interface power supply (VccD) and OP amplifier power supply (VccA), D/A converter
power supply (VccD)
•Analog output capability from 0 V to VccA
•Serial data I/O operates to maximum of 2.5 MHz (in cascade connection, up to 2.5 MHz when VccD = 5 V, up
to 1.5 MHz when VccD = 3 V)
•CMOS process
•Choice of two packages: SDIP-24 pin and SSOP-24 pin.
