Press Release Summary:
Supplied in 2.1 x 2 mm 6-lead package, LTC2630 series is comprised of 12-, 10-, and 8-bit DACs that offers choice of internal 2.5 or 4.096 V, 10 ppm/Â°C FS reference. Single voltage output DACs exhibit Â±1 LSB max integral nonlinearity error and suit under the hood automotive voltage adjustment. Specified over -40 to +125Â°C, IC communicates via 3-wire SPI-compatible serial interface at clock rates up to 50 MHz. Output settles for half-scale step in less than 5 Âµs.

12-Bit/10-Bit/8-Bit Voltage Output DAC Family Integrates Internal Reference in Tiny SC70 Package
MILPITAS, CA - June 4, 2007 - Linear Technology Corporation introduces the LTC2630, a family of 12-bit, 10-bit and 8-bit digital-to-analog converters (DACs) in tiny 2.1mm x 2mm SC70 packages - the smallest available DACs with an internal reference. The LTC2630 offers the choice of an internal 2.5V or 4.096V 10ppm/°C full-scale reference, providing nearly a 50% board space reduction over competing DACs with an internal reference. These single voltage output DACs achieve 12-bit DC performance of ±1LSB(max) integral nonlinearity error. The LTC2630 is ideal for "under the hood" automotive voltage adjustment, as it is guaranteed for operation over the H-grade temperature range (-40°C to +125°C), in addition to the I grade (-40°C to +85°C) and C-grade (0°C to +70°C) temperature ranges. With its tiny SC70 package, internal reference, and resolution options, the LTC2630 family can be used in a wide range of portable and space-constrained applications including battery-powered, consumer and process control equipment.
The low-power LTC2630 draws only 160uA of supply current at 3V and 180uA at 5V. Communicating via a 3-wire SPI-compatible serial interface at clock rates up to 50MHz, the LTC2630 DAC output settles for a half-scale step in less than 5us. Operating from a single 2.7V to 5.5V supply, the output can swing to the internal reference voltage or rail-to-rail to the supply voltage. The DAC outputs can power up to zero-scale or mid-scale, allowing more flexibility for designs that cannot be forced to ground when power is first applied.
The LTC2630-12, LTC2630-10, and LTC2630-8 are pin-compatible 12-bit, 10-bit, and 8-bit DACs, respectively. They are all available today in 6-pin SC70 packages, offering a pin- and software-compatible family for performance/cost optimization. Pricing begins at $1.43 each for the LTC2630-12, $1.24 each for the LTC2630-10, and $0.98 each for the LTC2630-8 in 1,000-piece quantities.
