10-Bit A/D Converter with Serial Interface
- -
CMOSThese ratiometric 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 accommo-
dated.
The MC145050 has the same pin out as the 8-bit MC145040 which allows an
external clock (ADCLK) to operate the dynamic A/D conversion sequence. The
MC145051 has the same pin out as the 8-bit MC145041 which has an internal
clock oscillator and an end-of-conversion (EOC) output. 11 Analog Input Channels with Internal Sample-and-Hold Operating Temperature Range: – 40 to 125°C Successive Approximation Conversion Time:
MC145050 — 21 μs (with 2.1 MHz ADCLK)
MC145051 — 44 μs Maximum Maximum Sample Rate: MC145050 — 38 ks/s
MC145051 — 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
