MB88146A
DESCRIPTION
• 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
• 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
• CMOS process
• Choice of two packages: SDIP-24 pin and SSOP-24 pin.
PACKAGES
The MB88146A is an 8-bit D/A converter with twelve built-in channels. The 12 analog outputs each have a built-
in OP amplifier with large current drive-capability.
The data input/output format is CS (chip select) with serial bus connection available.
A built-in 12-bit I/O expander enables serial
output).
This product can be used for microcontroller port expansion, electronic level adjustment, replacement of semi-
fixed resistance for tuning, etc.
