1 / 15 page www.lansdale.com Page 1 of 15 Issue A ML145053 10-Bit A/D Converter With Serial Interface CMOS Legacy Device: Motorola MC145053 This ratiometric 10-bit ADC has a serial interface port to provide commu- nication with MCUs and MPUs. Either a 10- or 16-bit format can be used. The16-bit format can be one continuous 16-bit stream or two intermittent 8- bit streams. The converter operates from a single power supply with no exter- nal trimming required. Reference voltages down to 4.0 V are accommodated. The ML145053 has an internal clock oscillator to operate the dynamic A/D conversion sequence and an end-of-conversion (EOC) output. • 5 Analog Input Channels with Internal Sample-and-Hold • Operating Temperature Range: TA – 40 to 125°C • Successive Approximation Conversion Time: 44 µs Maximum • Maximum Sample Rate: 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 DataPorts • 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 BLOCK DIAGRAM MICROWIRE is a trademark of National Semiconductor Corp.
