| Features, Applications |
The Fujitsu an 8-bit D/A converter capable of low-voltage operation, and designed with a built-in amp on each of its 12 analog output lines for large-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 replacement of semi-fixed resistors in tuning systems. In addition, the MB88346L is both function-compatible and pin-compatible with the MB88346B now in use, allowing easy substitution of the MB88346L for reduced supply voltage. Low voltage operation (VCC/VDD: 3.6 V) Ultra-low power consumption (0.5 mW/ch at VCC 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 VCC 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, SOP 20-pin, SSOP 20-pin. Pin No. 17 Symbol DI I/O I Function Serial address/data input to the internal 12-bit shift register: The address/data format is that upper 4 bits to D8) indicate an address and lower 8 bits 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). Load strobe input for a 12-bit address/data: A high level on the LD pin latches a 4-bit address (upper 4 bits: D8) of the internal 12-bit shift register into the internal address decoder, and writes 8-bit data (lower 8 bits: D0) of the shift register into an internal data latch selected by the latched address. 8-bit D/A output pins with OP amps. MCU interface and OP amp power supply pin. MCU interface and OP amp ground pin. D/A converter power supply pin. D/A converter ground pin. |
