FUJITSU MICROELECTRONICS DATA SHEET DS04-13512-2Ea Linear IC converter CMOS D/A Converter for Digital Tuning (8-channel, 8-bit, on-chip OP amp, low-voltage) MB88347L ■ DESCRIPTION The MB88347L incorporates eight 8-bit D/A converter modules. This device operates at low supply voltage in the performance guarantee range from 2.7 to 3.6 V. It also contains an output amplifier, allowing driving at large current. Since the MB88347L inputs data in serial mode, it requires only three control lines for data input and two or more MB88347L units can be cascaded. The MB88347L is function and pin compatible with the MB88347 (5-volt supply voltage model). The MB88347L can therefore easily replace the MB88347 in a system, thereby reducing the system’s voltage requirement. The MB88347L is the best replacement for electronic variable resistors or screwdriver control resistors. ■ FEATURES • • • • • • • Ultra-low power consumption (0.5 mW/ch: typical) Low voltage operation (VCC = 2.7 to 3.6 V) Ultra-compact space-saving package (SSOP-16) Contains 8-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 V 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 • CMOS process • Package lineup includes DIP 16-pin, SOP 16-pin, SSOP 16-pin ■ PACKAGES 16 pin, Plastic DIP (DIP-16P-M04) 16 pin, Plastic SOP 16 pin, Plastic SSOP (FPT-16P-M06) (FPT-16P-M05) Copyright©2000-2008 FUJITSU MICROELECTRONICS LIMITED All rights reserved 2000.1 MB88347L ■ PIN ASSIGNMENT (Top view) VSS 1 16 GND AO2 2 15 AO1 AO3 3 14 DI AO4 4 13 CLK AO5 5 12 LD AO6 6 11 DO AO7 7 10 AO8 VDD 8 9 VCC (DIP-16P-M04) (FPT-16P-M06) (FPT-16P-M05) ■ PIN DESCRIPTION 2 Pin No. Pin name I/O Functions 14 DI I Serial data input pin. This pin inputs serial data with a data length of 12 bits. (Do not leave the pin floating.) 11 DO O This pin outputs the MSB data in the 12-bit shift register at the CLK falling edge. 13 CLK I Shift clock input pin. The input signal from the DI pin enters the 12-bit shift register at the rising edge of the shift clock pulse. (Do not leave this pin floating.) 12 LD I When the LD pin inputs the High-level signal, shift register value is loaded to the decoder and the D/A output register. (Do not leave this pin floating. When data is not transferred, fix the pin to the “Low” level.) 15 2 3 4 5 6 7 10 AO1 AO2 AO3 AO4 AO5 AO6 AO7 AO8 O 8-bit D/A output with op amp. 9 VCC — MCU interface and OP amp power-supply pin. 16 GND — MCU interface and OP amp GND pin. 8 VDD — D/A converter reference power (High) input pin. 1 VSS — D/A converter reference power (Low) input pin.
