10-bit DAC in a TSOT-23-8 footprint
The LTC2640ITS8-HM10#TRMPBF is an Analog Devices 10-bit digital-to-analog converter delivering a buffered voltage output through an SPI interface. Housed in a TSOT-23-8 package, it occupies minimal board area — the 0.65 mm pitch and 2.9 × 2.8 mm footprint fit tight analog output channels where a larger SOIC or MSOP would crowd the routing. Operating from a single 5 V supply on both the analog and digital rails, the part integrates the reference and output buffer, reducing external component count to a few bypass caps.
What the INL and settling time mean for your signal chain
Integral nonlinearity is rated at ±0.2 LSB typical and ±0.5 LSB maximum — this is a 10-bit part, so ±0.5 LSB means the transfer curve stays within half a least-significant-bit of ideal across the full output range, which avoids missing codes in open-loop calibration or trim-DAC applications. The 4.2 µs typical settling time to ±0.5 LSB sets the update rate ceiling: at 10 bits, the DAC can be updated at roughly 240 kHz and still settle to the accuracy the INL spec guarantees.
ROHS3 compliant per the manufacturer's declaration, with no exemptions that would restrict EU or UKCA market placement.
