The LTC3568 is a constant frequency, synchronous step-down DC/DC converter. It is intended for medium power applications, operating from a 2.5V to 5.5V input voltage range. The device has a user-configurable operating frequency up to 4MHz, allowing the use of tiny, low cost capacitors and inductors 2mm or less in height. The output voltage is adjustable from 0.8V to 5V. Internal sychronous 0.11Ω power switches with 2.4A peak current ratings provide high effi ciency. The LTC3568’s current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. The LTC3568 can be confi gured for automatic power sav- ing Burst Mode operation to reduce gate charge losses when the load current drops below the level required for continuous operation. For reduced noise and RF interfer- ence, the SYNC/MODE pin can be confi gured to skip pulses or provide forced continuous operation. To further maximize battery life, the P-channel MOSFET is turned on continuously in dropout (100% duty cycle) with a low quiescent current of 60μA. In shutdown, the device draws <1μA.

The LTC ®2411/LTC2411-1 are 2.7V to 5.5V micropower 24-bit differential ∆Σ analog-to-digital converters with an integrated oscillator, 2ppm INL and 0.29ppm RMS noise. They use delta-sigma technology and provide single cycle settling time for multiplexed applications.

The LTC2411 and LTC2411-1 are identical when driven by an external oscillator. The internal oscillator requires no external frequency setting components. The converters accept any external differential reference voltage from 0.1V to VCC for flexible ratiometric and remote sensing measurement configurations. The full- scale differential input range is from –0.5VREF to 0.5VREF. The reference common mode voltage, VREFCM, and the input common mode voltage, VINCM, may be indepen- dently set anywhere within the GND to VCC range of the LTC2411/LTC2411-1. The DC common mode input rejec- tion is better than 140dB. The LTC2411/LTC2411-1 communicate through a flexible 3-wire digital interface that is compatible with SPI and MICROWIRE TM protocols.

The CS5101A and CS5102A are 16-bit monolithic CMOS analog-to-digital converters (ADCs) capable of 100 kSps (5101A) and 20 kSps (5102A) throughput. The CS5102A’s low power consumption of 44mW, coupled with a power-down mode, makes it particularly suitable for battery-powered operation. On-chip self-calibration circuitry achieves nonlinearity of ±0.001% of FS and guarantees 16-bit, no missing codes over the entire specified temperature range. Superior linearity also leads to 92 dB S/(N+D) with harmonics below -100 dB. Offset and full-scale errors are minimized during the calibration cycle, eliminating the need for external trimming. The CS5101A and CS5102A each consist of a 2-channel input multiplexer, DAC, conversion and calibration microcontroller, clock generator, comparator, and serial communications port. The inherent sampling architecture of the device eliminates the need for an external track-

The ADS1212 and ADS1213 are precision, wide dynamic range, delta-sigma Analog-to-Digital (A/D) converters with 24-bit resolution operating from a single +5V supply. The differential inputs are ideal for direct connection to transducers or low-level voltage signals. The delta-sigma architecture is used for wide dynamic range and to ensure 22 bits of no-missing-code performance. An effective resolution of 20 bits is achieved through the use of a very low-noise input amplifier at conversion rates up to 10Hz. Effective resolutions of 16 bits can be maintained up to a sample rate of 1kHz through the use of the unique Turbo Modulator mode of operation. The dynamic range of the converters is further increased by providing a low-noise programmable gain amplifier with a gain range of 1 to 16 in binary steps. The ADS1212 and ADS1213 are designed for high-resolution measurement applications in smart transmitters, industrial process control, weigh scales, chromatography and portable instrumentation. Both converters include a flexible synchronous serial interface that is SPI compatible.
