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
