D/A Converter for Digital Tuning
(8-channel, 8-bit, on-chip OP amp, low-voltage)
MB88347L
s 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.

s PIN DESCRIPTION
Pin No. 14 11 13 Pin name DI DO CLK I/O I O I Functions Serial data input pin. This pin inputs serial data with a data length of 12 bits. (Do not leave the pin floating.) This pin outputs the MSB data in the 12-bit shift register at the CLK falling edge. 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.) 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.)
