D/A Converter for Digital Tuning

(12-channel, 8-bit, on-chip OP amp, low-voltage)

MB88346L

■ DESCRIPTION

The Fujitsu Microelectronics MB88346L is a 12-channel 8-bit D/A converter capable of low-voltage operation that

has amplifiers built into each of the 12 analog output lines to deliver heavy-current drive capability.

The use of serial data input means that only three control lines are required, and enables cascade connection of

multiple MB88346L chips.

The MB88346L is suitable for applications such as electronic volume controls and replacing trimmer potentiom-

eters in tuning systems. In addition, the MB88346L is both function-compatible and pin-compatible the currently

used MB88346B, making it easy to reduce the voltage level of a system by simply replacing the MB88346B with

the MB88346L.

■ FEATURES

• Low voltage operation (VCC/VDD : 2.7 V to 3.6 V)

• Ultra-low power consumption (0.5 mW/ch at V^CC= 3 V)

• Ultra-compact space-saving package lineup (SSOP-20)

• Contains 12-channel R-2R type 8-bit D/A converter

• On-chip analog output amps (sink current max. 1.0 mA, source current max. 1.0 mA)

• Analog output range from 0 to V^CC

• Two separate power supply/ground lines for MCU interface block/operational amplifier output buffer block and

D/A converter block

• Serial data input : maximum operating speed 2.5 MHz

(maximum operating speed in cascade connection is 1.5 MHz)

• CMOS process

• Package lineup includes DIP 20-pin, SSOP 20-pin

Function

Serial address/data input to the internal 12-bit shift register : The ad-

dress/data format is that upper 4 bits (D11 to D8) indicate an address

and lower 8 bits (D7 to D0) indicate data. The D11 (MSB) is the first-

in bit and D0 (LSB) is the last-in bit.

Outputs MSB bit data from 12-bit shift register.

Shift clock input to the internal 12-bit shift register : At the rising edge

of CLK data on the DI pin is shifted into the LSB of the shift register

and contents of the shift register are shifted right (to the MSB) .

CLK

Load strobe input for a 12-bit address/data : A high level on the LD pin

latches a 4-bit address (upper 4 bits : D11 to D8) of the internal 12-bit

shift register into the internal address decoder, and writes 8-bit data

(lower 8 bits : D7 to D0) of the shift register into an internal data latch

selected by the latched address.

■ DATA CONFIGURATION

The MB88346L has a 12-bit shift register for controlling the chip. The data passed to the 12-bit shift register

needs to be supplied in the following format.

The data structure consists of a total of 12 bits, four for address selection and eight for D/A data output.
