www.DataSheet4U.com ML145040 ML145041 8-Bit A/D Converters With Serial Interface Silicon-Gate CMOS SEMICONDUCTOR TECHNICAL DATA Legacy Device: Motorola MC145040, MC145041 The ML145040 and ML145041 are low-cost 8-bit A/D Converters with serial interface ports to provide communication with microprocessors and microcomputers. The converters operate from a single power supply with a maximum nonlinearity of ± 1/2 LSB over the full temperature range. No external trimming is required. The ML145040 allows an external clock input (A/D CLK) to operate the dynamic A/D conversion sequence. The ML145041 has an internal clock and an end–of–conversion signal (EOC) is provided. Operating Voltage Range: VDD = 4.5 to 5.5 Volts Successive Approximation Conversion Time: ML145040 – 10 µs (with 2 MHz A/D CLK) ML145041 – 20 µs Maximum (Internal Clock) 11 Analog Input Channels with Internal Sample and Hold 0- to 5-Volt Analog Input Range with Single 5-Volt Supply Ratiometric Conversion Separate Vref and VAG Pins for Noise Immunity Wide Vref Range No External Trimming Required Direct Interface to Motorola SPI and National MICROWIRE Serial Data Ports TTL/NMOS–Compatible Inputs May be Driven with CMOS Outputs are CMOS, NMOS or TTL Compatible Very Low Reference Current Requirements Low Power Consumption: 11 mW Internal Test Mode for Self Test P DIP 20 = RP CERAMIC PLASTIC CASE 732 CASE 738 SO 20W = -6P SOG CASE 751D CROSS REFERENCE/ORDERING INFORMATION PACKAGE MOTOROLA L...
