LTC2632AHTS8-HI12 Dual 12-Bit SPI DAC A Grade Wide Swing 8-Lead TSOT-23 Integrated Circuit Chip

The LTC2632AHTS8-HI12 is a dual 12-bit voltage output digital to analog converter from the LTC2632 family, supplied in a 8-Lead TSOT-23 package. It uses an SPI interface and a 4.096 V internal reference, giving two buffered channels for wide output swing in a compact outline.

The LTC2632AHTS8-HI12 reference is trimmed to 10 ppm per degree C, and the A grade holds linearity across the full 12-bit code range. Output noise is 0.75 mV peak to peak from 0.1 Hz to 200 kHz, and the converter is monotonic over its rated temperature range. This is the linearity bin published for the LTC2632.

Data is written through the SPI port into double-buffered latches, so a channel can be preloaded and then released with a single update. Power-on reset options of zero scale, midscale and high impedance define the output state before the first command.

The LTC2632AHTS8-HI12 operates from 2.7 V to 5.5 V and draws 0.4 mA at 3 V, which suits battery powered and loop powered designs. Where a system reference exists, the LTC2632 internal reference can be overdriven so both channels share the same full-scale voltage. Interface timing for the LTC2632 is specified in the manufacturer data sheet.

Every order of the LTC2632AHTS8-HI12 ships in 8-Lead TSOT-23 packaging with full traceability, RoHS compliant and lead free, and samples plus volume pricing are available on request. The LTC2632AHTS8-HI12 is held in stock for wide output swing applications.
