Power can be drawn from RFOUT6 terminal for external use, up to a maximum load current of 50mA. (13) Variable bias regulator This regulator uses the voltage generated by VREGIN terminal (pin 67) to produce an amplified output voltage at VREGOUT terminal (pin 68). Power can be drawn from VREGOUT terminal for external use, up to a maximum load current of 10mA. (14) D/A converter D/A1 to D/A3 converter process 8 bit input signal and D/A4 converter processes 10 bit input signal. This converter generates an output voltage (0.5 to 2.5V ) at D/AOUT1 terminal (pin 63) to D/AOUT4 terminal (pin 60) according to the signal from serial control. (15) Power-on reset When the OUT1 terminal (pin 75) voltage exceeds 2.75V(typ.) , after a delay interval set by a capacitor (0.1 F typ.) connected to the CTP terminal (pin 76) , the RESET terminal (pin 77) voltage becomes "H" level from "L" level and the reset signal is canceled.

(2) When the CTP terminal (pin 76) voltage exceeds 1.23V (typ.), the reset is canceled. (The RESET terminal voltage becomes "H" level from "L" level.: rising time from 10% to 90% = tr) (3) When OUT1 terminal voltage falls below detected rising voltage (2.685V typ.), the CTP terminal voltage is down and the reset signal is output. (RESET terminal voltage becomes "L" level from "H" level.) (4) When OUT1 terminal voltage exceeds rising voltage detect, charging of CTP is started. (5) When CTP terminal voltage rises above threshold voltage, the reset is canceled. (6) When OUT1 terminal voltage falls below the voltage detect, the reset signal is output. SETTING OF HOLD TIME FOR POWER-ON RESET According to the time constant set by capacitor (CTP) connected to CTP terminal (pin 76), rise time (hold time) of RESET terminal (pin 77) voltage can be set after OUT1 terminal (pin 75) voltage exceeds 2.75V (typ.).

After mounting, printed circuit boards should be stored and shipped in conductive bags or Containers. Work platforms, tools, and instruments should be properly grounded. Working personal should be grounded with resistance of 250 k to 1 M between body and ground. * Do not apply negative voltages The use of negative voltages below -0.3V may create parasitic transistors on LSI lines, Which can cause abnormal operation.
