Philips Semiconductors Linear Products Product specification 10-Bit µP-compatible D/A converter NE5020 DESCRIPTION The NE5020 is a microprocessor-compatible monolithic 10-bit digital-to-analog converter subsystem. This device offers 10-bit resolution and ±0.1% accuracy and monotonicity guaranteed over full operating temperature range. Low loading latches, adjustable logic thresholds, and addressing capability allow the NE5020 to directly interface with most microprocessor- and logic-controlled systems. The NE5020 contains internal voltage reference, DAC switches and resistor ladder. Also, the input buffer and output summing amplifier are included. In addition, the matched application resistors for scaling either unipolar or bipolar output values are included on a single monolithic ch [ ... ]
