Quad 8-bit DAC with 6 µs settling — what it means for the loop
The MAX5100BEUP+T from Analog Devices packs four independent 8-bit voltage-output DACs into a 20-TSSOP package. Each channel settles to within 1 LSB in 6 µs typical, which keeps update rates practical for closed-loop trim, calibration DACs, and multi-channel set-point generation. The parallel data interface writes all four channels directly, so no serial latency stacks up when you need simultaneous updates across outputs. Supply range runs from 2.7 V to 5.5 V on both the analog and digital pins — one rail does both. The external reference input sets the output span.
String DAC architecture and output drive
The internal architecture is a string DAC — a resistor ladder with switches that tap the divider nodes. This gives monotonicity by design and keeps the INL within ±2 LSB max, DNL within ±1 LSB max. The buffered voltage output can drive the input of an ADC or a control node directly; no external op-amp needed for the typical load.
Temperature range and environment
Rated for -40°C to 85°C, the MAX5100BEUP+T covers industrial control cabinets, outdoor telecom gear, and automotive cabin environments. The 20-TSSOP package is a surface-mount footprint common on mixed-signal boards; the tape-and-reel option (TR suffix) feeds pick-and-place lines directly.
