Its 12-bit resolution means the output voltage is divided into 4096 steps — for a 2.5 V reference, each step is about 610 µV. The ±1 LSB max INL and DNL guarantee monotonicity across all codes, so the output never steps backward as the digital input increments. Settling time is 4.1 µs typical to within 1 LSB for a full-scale step — this sets the maximum update rate at roughly 240 kHz. For applications like closed-loop servo trim or waveform generation below that frequency, the DAC can be updated directly without external hold circuitry. The buffered output can drive a few mA directly into an ADC reference input or a control node; for heavier loads, an external buffer may be needed. ## Package and board-fit — TSOT-23-8 The part comes in a TSOT-23-8 package (Supplier Device Package TSOT-23-8), a thin SOT-23 variant with 8 leads. The package is surface-mount and supplied in Tape & Reel (TR) or Cut Tape (CT) — standard for automated pick-and-place. ## Lifecycle and compliance — active and ROHS3 It is ROHS3 compliant, meeting the current EU RoHS exemption rules.","metaTitle":"LTC2640ITS8-LZ12#TRMPBF 12-bit DAC, SPI, TSOT-23-8","metaDescription":"Analog Devices LTC2640ITS8-LZ12#TRMPBF 12-bit buffered voltage-output DAC with SPI interface, 4.1 µs settling time, TSOT-23-8.
