1 / 15 page MC145053 MOTOROLA WIRELESS SEMICONDUCTOR SOLUTIONS DEVICE DATA 1 10Bit A/D Converter with Serial Interface CMOS This ratiometric 10-bit ADC has a serial interface port to provide communi- cation 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 converter operates from a single power supply with no external trimming required. Reference voltages down to 4.0 V are accommodated. The MC145053 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: – 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 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 BLOCK DIAGRAM SUCCESSIVE APPROXIMATION REGISTER 2 3 4 5 6 12 11 1 10 13 10-BIT RC DAC WITH SAMPLE AND HOLD DATA REGISTER 98 VAG Vref AUTO-ZEROED COMPARATOR MUX ADDRESS REGISTER DIGITAL CONTROL LOGIC INTERNAL TEST VOLTAGES AN0 AN1 AN2 AN3 AN4 AN5 AN6 AN7 CS Din Dout SCLK EOC MUX OUT PIN 14 = VDD PIN 7 = VSS ANALOG MUX MICROWIRE is a trademark of National Semiconductor Corp.
