12-bit DAC in a six-pin SOT-23 — what it means on the bench
The MAX5812NEUT-T is a single-channel, 12-bit voltage-output DAC with a 2-wire I²C serial interface, packed in a SOT-23-6. That six-pin package is about the size of a grain of rice — easy to hand-place and rework with hot air if you keep the nozzle off the plastic body. The 12 µs settling time means it can update a control loop at roughly 80 kHz without the output lagging the setpoint.
Supply rails and temperature range — one-rail simplicity
That keeps the board routing clean and the decoupling simple: one 0.1 µF cap close to the pin is usually enough.
Linearity and output — what the ±2 LSB INL means
Maximum INL is ±2 LSB, DNL is ±1 LSB. For a 12-bit DAC with a 5 V reference, that translates to about ±2.4 mV integral error and ±1.2 mV differential error — acceptable for many open-loop trim and set-point applications without software calibration. The output is voltage-buffered, so it can drive a few mA directly into an ADC input or an op-amp summing node.
