MAX5438EUB规格书详情
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.
