www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-13400-2E LINEAR IC FREQUENCY-TO-VOLTAGE CONVERTER MB4206 FREQUENCY-TO-VOLTAGE CONVERTER WITH SINGLE POWER SUPPLY COMPARATOR The Fujitsu MB4206 is a frequency-to-voltage converter with an on-chip comparator. The MB4206 uses a charge pump driven by a positive-edge Schmitt trigger/flip-flop input so stable operation is achieved against noise signal input. The output of the comparator is zener-clamped to a reference voltage; thus, a precise hysteresis output is obtained. The overall design makes the circuit fairly tolerant of imperfections in the input waveform. • Conversion coefficient determined by RC pair: VO(F) = FIN • RT • CT • VR • Positive edge-triggered frequency input • Equal internal reference high-level ouput and comparator high level output • Package - 8-pin plastic SIP package (Suffix: -PS) PLASTIC PACKAGE (SIP-08P-M03) PIN ASSIGNMENTS s ABSOLUTE MAXIMUM RATINGS (see NOTE) Rating Symbol VCC VCC(S) IZ PD TOP TSTG Value 24 40 (t ≤ 50ms) 20 300 (Ta ≤ 85°C) -30 to +85 -55 to +125 (Ta= 25°C) Unit V V mA mW F/V 8 + OUT(C) +IN(C) VO(F) /-IN(C) VR GND TC IN(F) V CC 7 6 5 4 3 2 1 _ Power Supply Voltage Surge Voltage at VCC Zener Current Power Dissipation Operating Temperature Storage Temperature NOTE: °C °C Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded.
