General Description
The Maxim MX7537/MX7547contain two 12-bit current-
output multiplying digital-to-analog converters (DAC)
in a single package. Input level shifters. data registers
and control logic make microprocessor interfacing
straightforward. Operation is from a single +12V to
+15V power supply maintaining TTL, 74HC and 5V
CMOS logic compatibility.
The MX7547 accepts CSA, CSB, WR control signals
and 12 data inputs for DAC selection and full parallel
data loading. The MX7537 receives data_in 2 bytes,
using a right justified 8+4 format. AO, A1, cs, WR and
UPD signals provide full control for DAC selection
and data loading.
Each of the DACs in the MX7537/MX7547 provides 4-
quadrant multiplication capabilities and separate ref-
erence input and feedback resistor pins. The MX7537
additionally makes available separate AGND pins for
applications where each DAC is biased at a different
voltage. Since both DACs are on a single monolithic
chip, matching and temperature tracking between
them is excellent. Gain error is specified at less than
it LSB, and 12-bit linearity and monotonicity are
guaranteed over the full operating temperature ranges.
Maxim's MX7537 and MX7547 are available in narrow
24-lead 0.3" DIP and Wide so, as well as, 28-pin-lead
PLCC packages.
