MB4053

FUJITSU SEMICONDUCTOR DATA SHEET DS04-13103-6E Linear IC 6-Channel 8-BIT A/D Converter MB4053 s DESCRIPTION The Fujitsu MB4053 is 6-channel, 8-bit, single-slope A/D converter subsystem designed to be used in a microprocessor based data control system. The MB4053 is single monolithic bipolar IC providing a 1 of 8 address decoder, 8-channel analog multiplier, sample and hold, constant current generator, ramp integrator and comparator in a 16-pin package. This A/D converter subsystems are suitable for a wide range of applications. The resolution required by an application can be obtained by arbitarily selecting a suitable integration time. Also zero offset and full-scale error corrections can be made automatically (auto-zero and auto-calibration) to minimize conversion error. s FEATURES Microprocessor compatible Digital input/output: TTL compatible Zero offset and full-scale error correction capability Ratiometric conversion capability Available in 16-pin DIP and Flat Package Compatible with MC 14443 and µA9708 (DIP package) Single power supply: +4.75 V to +15 V Excellent Iinearity: ±0.2% max. error Fast conversion time: 300 µs/ch typ. Analog input volgage: 0 V to VCC – 2 V (5.25 V max.) Power Dissipation: 25 mW typ. at VCC = 5 V s PACKAGES 16-pin Plastic DIP 16-pin Plastic SOP (DIP-16P-M04) (FPT-16P-M06) MB4053 s PIN ASSIGNMENT (Top view) A1 A2 RAMP START CH GND RREF RAMP STOP VREF 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 A0 I1 VCC I2 I3 I4 I5 I6 (...
