ES52110

ITRI ERSO Features On-Chip Latches for Both DACs. +5V to +12V Operation . DACs Matched to 1%. Four Quadrant Multiplication. TTL/CMOS Compatibel from 5V to 12V. Full Temperature Operation. 8-bit Endpoint Linearity(+1/2 LSB) Microprocessor Compatible. ES52110 8-bit D/A Converter DESCRIPTION ES52110 contains two & two 8-bit multiplying D/A converter in a single chip.This monolithic construction offers excellent DACto DAC matching and trzcking. The ES 52110 consists of two R-2R resistor-ladder networks, two tracking span resistors, two data latches, one input buffer, and control logic circuit, Both DACs offer excellent four quadrant multiplication characteristics with a separated reference input and feedback resistor for each DAC.
