Title:
MULTICHANNEL ANALOG-TO-DIGITAL CONVERTER
Document Type and Number:
Japanese Patent JPH03183214
Kind Code:
A
Abstract:
PURPOSE: To form an interface on a single chip by mounting an ADC on a single chip by the use of a compact and low power ADC array and a register to transfer digital data to an output part and forming throughput similar to that of a high speed single ADC. CONSTITUTION: A control logic device 20 receives a clock and a start/stop synchronizing signal and provides signals for various analog channels 10 and shift registers 18, external synchronizing signal and a stop strobe. The output port of a shift register is connected to an output buffer 23, which sends a signal to an external bus. On-chip bias generators 22A, 22B apply bias voltage to the analog channels 10. Since each ADC 16 in each analog channel 10 includes an ADC capacitor array to be the maximum single element in the channel 10, 64 ADCs are integrated on the same chip by minimizing the size of the array.
