The LTC1408 is a 14-bit, 600ksps ADC with six simultaneously sampled differential inputs. The device draws only 5mA from a single 3V supply, and comes in a tiny 32 pin (5mm ? 5mm) QFN package. A SLEEP shutdown feature lowers power consumption to 6?W. The combination of low power and tiny package makes the LTC1408 suitable for portable applications.The LTC1408 contains six separate differential inputs that are sampled simultaneously on the rising edge of the CONV signal. These six sampled inputs are then converted at a rate of 100ksps per channel.The 90dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source.The device converts 0V to 2.5V unipolar inputs differentially, or ?1.25V bipolar inputs also differentially, depending on the state of the BIP pin. Any analog input may swing rail-to-rail as long as the differential input range is maintained.The conversion sequence can be abbreviated to convert fewer than six channels, depending on the logic state of the SEL2, SEL1 and SEL0 inputs.The serial interface sends out the six conversion results in 96 clocks for compatibility with standard serial interfaces.Applications Multiphase Power Measurement Multiphase Motor Control Data Acquisition Systems Uninterruptable Power Supplies

The LTC6905 precision, programmable silicon oscillator is easy to use and occupies very little board space. It requires only a single resistor to set the output frequency from 17MHz to 170MHz with a typical frequency error of 0.5% or less.The LTC6905 operates with a single 2.7V to 5.5V power supply and provides a rail-to-rail, 50% duty cycle square wave output. The CMOS output driver ensures fast rise/fall times and rail-to-rail switching. Operation is simple: A single resistor, RSET, between 10K to 25K is used to set the frequency, and an internal three-state divider (DIV input) allows for division of the master clock by 1, 2 or 4, providing three frequencies for each RSET value.The LTC6905 features a proprietary feedback loop that linearizes the relationship between RSET and frequency, eliminating the need for tables to calculate frequency. The oscillator can be easily programmed using the simple formula outlined below:See first page of Data Sheet for formula?For higher accuracy, fixed frequency versions that includean internal frequency-setting resistor, see the LTC6905-XXX Series datasheet.Applications High Frequency Precision Oscillator High Speed Data Bus Clock Fixed Crystal Oscillator Replacement Ceramic Oscillator Replacement

The LTC6900 is a precision, low power oscillator that is easy to use and occupies very little PC board space. The oscillator frequency is programmed by a single external resistor (RSET). The LTC6900 has been designed for high accuracy operation (?1.5% frequency error) without the need for external trim components. The LTC6900 operates with a single 2.7V to 5.5V power supply and provides a rail-to-rail, 50% duty cycle square wave output. The CMOS output driver ensures fast rise/fall times and rail-to-rail switching. The frequency-setting resistor can vary from 10k? to 2M? to select a master oscillator frequency between 100kHz and 20MHz (5V supply). The three-state DIV input determines whether the master clock is divided by 1, 10 or 100 before driving the output, providing three frequency ranges spanning 1kHz to 20MHz (5V supply). The LTC6900 features a proprietary feedback loop that linearizes the relationship between RSET and frequency, eliminating the need for tables to calculate frequency.
