M62383FP
5 V Composite Type D-A Converter
REJ03F0076-0100Z Rev.1.0 Sep.19.2003
Description
The M62383FP is a 5 V composite D-A converter incorporating two modules, with two 8-bit buffer amp output D-A converters and an 8-bit D-A converter for reference voltage adjustment as one module. The D-A outputs can be set simultaneously for each module without address setting. The data configurations comprise 16-bit serial data for the two main D-A circuits and 8-bit serial data for the reference voltage setting D-A. The D-A output buffer amps have full-swing output capability, from power supply voltage to GND.
Features
* * * * Simultaneous dual-output data setting by means of 16-bit serial data (TTL level) Data transfer clock frequency: 10 MHz (max.) D-A converter output settling time: 5 s (typ.) Power-on reset and external reset (L reset) functions (D-A output = 0 V, MON output = VREF x 255/256)
Application
Automatic adjustment of electronic devices
Recommended Operating Conditions
Power supply voltage: 5 V 10%

Usage Notes
1. This IC has three pins to which a constant voltage is applied during use (constant-voltage input pins: VCC, VREFx, VREFy). If ripples or spikes are imposed on these pins, D-A conversion accuracy may fall. When using this IC, a capacitor (1 F or higher recommended) must be inserted between the constant-voltage input pins and ground (GND) in order to ensure stable D-A conversion. 2. With regard to the reset function (power-on reset), when the power supply voltage passes the vicinity of 1.5 V at power-on, the D-A output voltage (VOA) becomes 0 V (D-A data: 00h), and the MON output voltage (VOR) becomes VREF x 255/256 (MON data: FFh), and output is maintained until the next data is set. In the event of repeated power supply on/off operations at short intervals, a reset may not be effected because of the simplicity of the circuit.
