ML145053

www.DataSheet4U.com 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 communication 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 8bit streams. The converter operates from a single power supply with no external 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 Vref MUX OUT VAG P DIP 14 = CP PLASTIC CASE 646 SOG 14 = -5P SOG CASE 751A CROSS REFERENCE/ORDERING INFORMATION MOTOROLA PACKAGE LANSDALE P DIP 14 MC145053P ML145053CP SOG 14 MC145053D ML145053-5P Note: Lansdale lead free (Pb) product, as it becomes available, will be identified by a part number prefix change fr...
