LTC2630 Single 12-/10-/8-Bit Rail-to- Rail DACs with 10ppm/C Reference in SC70 Features Description n Integrated Precision Reference The LTC 2630 is a family of 12-, 10-, and 8-bit voltage- 2.5V Full Scale 10ppm/C (LTC2630-L) output DACs with an integrated, high-accuracy, low-drift 4.096V Full Scale 10ppm/C (LTC2630-H) reference in a 6-lead SC70 package. It has a rail-to-rail n Maximum INL Error: 1 LSB (LTC2630A-12) output buffer and is guaranteed monotonic. n Low Noise: 0.7mV , 0.1Hz to 200kHz P-P The LTC2630-L has a full-scale output of 2.5V, and n Guaranteed Monotonic over Temperature operates from a single 2.7V to 5.5V supply. The n Selectable Internal Reference or Supply as Reference LTC2630-H has a full-scale output of 4.096V, and oper- n 2.7V to 5.5V Supply Range (LTC2630-L) ates from a 4.5V to 5.5V supply. Each DAC can also oper- n Low Power Operation: 180A at 3V ate in supply as reference mode, which sets the full-scale n Power Down to 1.8A Maximum (C and I Grades) output to the supply voltage. n Power-on Reset to Zero or Mid-Scale Options n The parts use a simple SPI/MICROWIRE compatible SPI Serial Interface n 3-wire serial interface which operates at clock rates up Double-Buffered Data Latches n to 50MHz. Tiny 6-Lead SC70 Package The LTC2630 incorporates a power-on reset circuit. a Options are available for reset to zero or reset to mid- scale after power-up. n Mobile Communications L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Analog n Process Control and Industrial Automation Devices, Inc.
