MB88146A

www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-13513-1E Linear IC Converter CMOS D/A Converter for Digital Tuning (12-channel, 8-bit, on-chip OP amp., low-voltage) MB88146A s DESCRIPTION The MB88146A is an 8-bit D/A converter with twelve built-in channels. The 12 analog outputs each have a builtin 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 ↔ parallel conversion (8 of the 12 bits can also be used for analog output). This product can be used for microcontroller port expansion, electronic level adjustment, replacement of semifixed resistance for tuning, etc. s 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 packa...
