MB40D001

■ DESCRIPTION

The MB40D001 is an 8-bit D/A converter with 12 built-in channels. The 12 sets of analog outputs have built-in

OP amps to enable use with large current drive applications.

CS(chipselect)datainput/outputformatisusedtoenableconnectiontoaserialbus. Abuilt-in12-bitI/Oexpander

provides serial <=> parallel conversion (8 of the 12 bits are also used with analog output).

The MB40D001 can be adapted for microcontroller port expansion, or replacement of electronic volume control

or semi-fixed calibration resistance.

Also, the MB40D001 is function- and pin-compatible with the MB88146A, for easy replacement when reducing

sysytem operating voltage.

■ FEATURES

• Supply voltage 2.7 V to 3.6 V (Power consumption 0.7 mW/ch typ.)

• Compact package: SSOP-24

• R-2R type 8-bit D/A converter with 12 built-in channels

• Built-in 12-bit I/O expander (8 of 12 bits also used with analog output)

• Built-in analog amplifier (sink current max. 0.4 mA, source current max. 1.0 mA)

• Built-in power-on detector circuit (detects VccD power-on, and performs initialization)

• Separate MCU interface power supply (VccD), OP amp supply (VccA), D/A converter supply V^DD

• Analog output range 0 V to VccA.

• Serial data input/output operation to maximum of 2.5 MHz (1.5 MHz in cascade operation)

• CMOS process
