1 / 15 page www.lansdale.com Page 1 of 15 ML145050 ML145051 10-Bit A/D Converter with Serial Interface - CMOS Legacy Device: Motorola MC145050, MC145051 These ratio metric 10-bit ADCs have serial interface ports to provide communication with MCUs and MPUs. Either a 10- or 16-bit format can be used. The 16-bit format can be one continuous 16-bit stream or two intermittent 8-bit streams. The converters operate from a single power supply with no external trimming required. Reference voltages down to 4.0 V are accommodated. The ML145050 has the same pin out as the 8-bit ML145040 which allows an external clock (ADCLK) to operate the dynamic A/D con- version sequence. The ML145051 has the same pin out as the 8-bit ML145041 which has an internal clock oscillator and an end-of-con- version (EOC) output. • 11 Analog Input Channels with Internal Sample-and-Hold • Operating Temperature Range: – 40 to 125°C • Successive Approximation Conversion Time: ML145050 – 21 µs (with 2.1 MHz ADCLK) ML145051 – 44 µs Maximum • Maximum Sample Rate: ML145050 – 38 ks/s ML145051 – 20.4 ks/s • Analog Input Range with 5-Volt Supply: 0 to 5 V • Monotonic with No Missing Codes • Direct Interface to Motorola SPI and National MICROWIRE Serial Data Ports • Digital Inputs/Outputs are TTL, NMOS, and CMOS Compatible • Low Power Consumption: 14 mW • Chip Complexity: 1630 Elements (FETs, Capacitors, etc.) • See Application Note AN1062 for Operation with QSPI MICROWARE is A Trademark Of National Semiconductor Corp.
