General Description
The MAX5436–MAX5439 are 128-tap high-voltage (±5V to ±15V) digital
potentiometers in packages that are half the size of comparable devices in
8-pin SO. They perform the same function as mechanical potentiometers, but
replace the mechanics with a simple digital interface. The digital logic is
powered by a separate single +2.7V to +5.25V supply voltage (VCC). The
resistor string uses its own analog supplies (VDD and VSS) that require VDD -
VSS to be greater than 9V and less than 31.5V. This allows for greater
flexibility in voltage ranges that can be used with these devices. Examples of
analog supply ranges include not only dual voltages of ±5V to ±15V, but
single-supply voltages, such as +10V, +15V, +30V, -30V, and more, as long as
the ranges of VDD - VSS and VCC - VSS are met.
The MAX5437/MAX5439 include an on-chip, high voltage, uncommitted amplifier,
providing additional reductions in board space and cost. Other features
include low 35ppm/°C end-to-end and 5ppm/°C ratio metric resistor temperature
coefficients, a 3-wire SPI™/QSPI™/MICROWIRE™-compatible serial interface, and
a power-on reset to midscale.
The MAX5436/MAX5438 are available in 10-pin µMAX packages. The MAX5437/MAX5439
are available in 14-pin TSSOP package. Each device is guaranteed over the
extended temperature range of -40°C to +85°C.
