Linear Technology | LTC2632 and LTC2633: 12-/10-/8-Bit Dual SPI/ I2C DACs Integrate 10ppm/°C Reference in Tiny Packages

MILPITAS, CA – March 15, 2011 – Linear Technology Corporation introduces the
LTC2632 and LTC2633 families of dual 12-bit, 10-bit and 8-bit rail-to-rail, voltage output digital-to-analog converters (DACs), with serial SPI (LTC2632) and I2C (LTC2633) interfaces. The LTC2632 and LTC2633 dual DACs complete Linear’s family of tiny 12-bit, 10-bit, and
8-bit voltage output DACs with internal references. The LTC263x family of single, dual, quad and octal DACs offers a versatile selection, featuring the smallest solution size for numerous trimming applications.
The LTC2632 and LTC2633 DACs offer accurate DC performance with a 12-bit INL of ±1LSB (max), ±5mV (max) offset error and ±0.8 % FSR (max) gain error. Notable AC performance includes fast 4.4µs settling time and low 2.8nV•s glitch impulse. Each dual DAC integrates a precision 10ppm/°C reference into a tiny 8-lead 3mm x 3mm TSOT-23 package. The devices’ small size and integrated reference offer space reduction for compact circuit boards, making them ideal for a variety of industrial, automotive, portable communications and ATE applications.
The LTC2632 and LTC2633 are available in a number of ordering options, allowing designers to select one of the three resolution options, and between a 2.5V (-L) or 4.096V (-H) full-scale output range, making them a good fit for 3V or 5V systems. The devices also offer zero or mid-scale power-on reset options, with the LTC2633-L additionally offering a high impedance (Hi-Z) output option, ideal for power supply margining applications. All options are guaranteed over the automotive (-40°C to +125°C) or commercial (0°C to +70°C) temperature ranges.
