产品概述

The MX7545A and MAX7645, 12-bit CMOS multiplying digital-to-analog converters (DAC) with internal data latches, are improved versions of the industry standard MX7545. The MX7545A features a 100ns max write pulse width (150ns for MAX7645) which allows interfacing to a wide range of fast 8- and 16-bit microprocessors. The MX7545A/MAX7645 are loaded by a single 12-bit wide word when active-low CS and active-low are both low. The active-low CS and active-low WR inputs can be connected low making the input data latches transparent and lowing unbuffered operation of these DACs.

The MX7545A is specified both with a single +5V and +15V power supply. With a +5V supply, the digital inputs are TTL and +5V-CMOS compatible with high voltage CMOS compatibility is maintained with a +15V supply. The MAX7645 is TTL and CMOS compatible with a +15V supply. Maxim MX7545A and MAX7645 use low tempco thin-film resistors laser trimmed to ±¼ LSB linearity and better than ±1 LSB gain accuracy. The digital inputs have improved protection against electrostatic discharge (ESD) damage and can typically withstand over 6,000V of ESD voltage. Both the MX7545A and the MAX7645 are supplied in 20-lead narrow DIP, surface mount Small Outline and PLCC packages.
