GENERAL DESCRIPTION
The TC7135 4-1/2 digit analog-to-digital converter (ADC)
offers 50 ppm (1 part in 20,000) resolution with a maximum
nonlinearity error of 1 count. An auto-zero cycle reduces zero
error to below 10
V and zero drift to 0.5V/°C. Source
impedance errors are minimized by a 10pA maximum input
current. Roll-over error is limited to
±1 count.
By combining the TC7135 with a TC7211A (LCD) driver,
a 4-1/2 digit display DVM or DPM can be constructed.
Overrange and underrange signals support automatic range
switching and special display blanking/flashing applications.
Microprocessor-based measurement systems are sup-
ported by BUSY, STROBE, and RUN/HOLD control signals.
Remote data acquisition systems with data transfer via UARTs
are also possible. The additional control pins and multiplexed
BCD outputs make the TC7135 the ideal converter for dis-
play or microprocessor-based measurement systems.
