General Description
The MX7545A and MAX7645, 12-bit CMOS multiplying
digitaI-to-analog converters (DAG) with internal data
latches, are improved versions of the industry stand-
ard MX7545. The MX7545A features a 100ns max write
pulse width (150ns for MAX7645) which allows inter-
facing to a wide range of fast 8- and 16-bit
microprocessors.
The MX7545A/MM7645_ige loaded by a single_12-bit
w_ide word when CS and WR are both low. The CS and
WR inputs can be connected low making the input
data latches transparent and allowing 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 while 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 :1/4LSB linearity and
better than 1-ILSB gain accuracy. The digital inputs
have improved protection against electrostatic dis-
charge (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.
