Speedy convertor samples six inputs
A low-power 14bit 600Ksample/s analogue-to-digital convertor has six simultaneous sampling differential inputs.
Linear Technology has introduced the LTC1408, a low-power 14bit 600Ksample/s analogue-to-digital convertor (ADC) with six simultaneous sampling differential inputs This three-wire serial ADC operates from a single 3V supply, with power dissipation typically 15mW

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.
The LTC1408 is available in a 32-pin (5 x 5mm) QFN package.
With less than one-tenth the power consumption and one-fifth the package size of the nearest competitor, the LTC1408 allows the design of compact, battery-powered and portable data acquisition systems.
The six simultaneously sampled differential inputs make this device the ideal choice for multiphase power measurement, multiphase motor control, data acquisition systems and UPSs.
When the LTC1408 is not converting, power dissipation can be further reduced to 3.3mW in nap mode with the internal 2.5V reference remaining active, and to 6uW in sleep mode, with all internal circuitry powered down.
The internal reference can also be overdriven with an external reference, up to the analogue supply voltage.
The LTC1408 uses three input-select lines to configure the number of differential inputs converted.
Thus, higher speeds are possible, from one differential input at 600Ksample/s to six differential inputs at 100Ksample/s.
The six conversion results are delivered sequentially to a high speed DSP serial port via a three-wire interface.
This ADC also features a separate digital output power supply pin and a bipolar/unipolar pin to select +/-1.25V bipolar or 0 to 2.5V unipolar input ranges.
The LTC1408 is available in the commercial and industrial temperature ranges. Request a free brochure from Linear Technology Corp ...
