MAX536BCWE+T

Digital To Analog Converters Overview

The MAX536BCWE+T is a quad, 12-bit voltage-output digital-to-analog converter (DAC) housed in a 16-pin Wide SO package. It integrates four precision output amplifiers and features factory calibration for ±1 LSB total unadjusted error. The device operates with a positive supply of +10.8V to +13.2V and a negative supply of -5V. It utilizes a double-buffered input structure with a 16-bit serial word compatible with SPI/QSPI or MICROWIRE interfaces. Key electrical parameters include a typical settling time of 3µs to ±0.5 LSB, a slew rate of 5V/µs, and a maximum power dissipation of 762mW at +70°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BE' indicates the extended temperature range (-40°C to +85°C), whereas 'BC' denotes the commercial range (0°C to +70°C). Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the Wide SOIC-16 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated analog channels are required within a single package. The dual reference inputs allow different full-scale ranges for paired DACs. Verify that the load impedance remains above 5kΩ to maintain specified dynamic performance. Ensure the system logic levels are compatible with the TTL/CMOS inputs.

Digital To Analog Converters Part Context

This part belongs to the MAX536/MAX537 family of calibrated, quad, 12-bit voltage-output DACs. The MAX536 variant specifically requires asymmetric supplies (+10.8V to +13.2V and -5V), distinguishing it from the MAX537 which uses ±5V supplies. The BC suffix identifies the commercial temperature grade.

Digital To Analog Converters Replacement Considerations

MAX536ACWE+T offers higher accuracy (±0.5 LSB TUE) but shares the same package and interface.

Digital To Analog Converters FAQ

How does the LDAC pin function in a 3-wire interface?

In a 3-wire interface configuration, the LDAC pin can be tied high or low. If tied high, DAC registers update via software commands; if tied low, they remain transparent to the input register changes.

What is the purpose of the TP pin?

The TP (Test Pin) must be connected to VDD for proper operation. It is intended for pre-production analysis and affects DAC functionality if left disconnected.

Can multiple MAX536 devices be daisy-chained?

Yes, any number of devices can be daisy-chained by connecting the SDO pin of one device to the SDI pin of the next, provided appropriate pull-up resistors are used for the MAX536's open-drain output.
