Tiny DACs go under the bonnet
Pin compatible 12, 10 and 8bit DACs come in tiny 2.1 x 2mm SC70 packages, making them the smallest available DACs with internal references.
Linear Technology has introduced the LTC2630, a family of 12, 10 and 8bit digital-to-analogue convertors (DACs) in tiny 2.1 x 2mm SC70 packages - the smallest available DACs with an internal reference The LTC2630 offers the choice of an internal 2.5 or 4.096V 10ppm/C full-scale reference, providing nearly a 50% board space reduction over competing DACs with an internal reference

Card power chip meets smart and SIM standards
The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
RF mixers take transformers onboard
Linear Technology has released two new high linearity up-converting RF active mixers with integrated RF transformers.
These single voltage output DACs achieve 12bit DC performance of +/-1LSB (maximum) integral nonlinearity error.
The LTC2630 is ideal for "under the bonnet" automotive voltage adjustment, as it is guaranteed for operation over the H-grade temperature range (-40 to +125C), in addition to the I-grade (-40 to +85C) and C-grade (0 to +70C) 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 three-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 2.7 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, 10, and 8bit DACs, respectively.
They are all available today in 6-pin SC70 packages, offering a pin- and software-compatible family for performance/cost optimisation.
Pricing begins at US $1.43 each for the LTC2630-12, $1.24 each for the LTC2630-10 and $0.98 each for the LTC2630-8 in 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
