Texas Instruments has introduced four dual-output SWIFT DC/DC step-down converters with integrated FETs that deliver 2 A and 3 A of continuous output current and support input voltages of 4.5 V to 28 V. The simple-to-design switchers, which come in a monolithic package, speed time to market, reduce external component count and help reduce cost for point-of-load systems used in a wide variety of applications including HDTVs, set-top boxes and othe...

Texas Instruments Incorporated (TI) today introduced a monolithic, filter-free, Class-D audio power amplifier with an integrated boost converter, which provides constant output power for portable applications such as personal navigation devices, PDAs, mobile phones, portable media players and handheld gaming devices. The combination of the 2.7-Watt (W) Class-D amplifier and integrated boost converter provides 85 percent overall efficiency, with l...

Texas Instruments has introduced a 4.5 V to 52 V wide-input voltage, non-synchronous boost controller, intended for applications where the output is a regulated current instead of a regulated voltage. The new TPS40211, demonstrated at the Light+Building Frankfurt show (April 6 – 11, 2008) at the “LED Light for you (LLFY) – powered by OSRAM” booth (Hall 4.1 / D31), allows designers to efficiently manage LED lighting, indust...

Texas Instruments Incorporated today introduced a precision power operational amplifier which operates on supplies up to 100V and delivers a high output current of ±50mA with a 150mA short circuit limit. The driving force for the OPA454 design was high-voltage test equipment, which requires a combination of high voltage with high DC accuracy and significant speed. Hence, the OPA454 is an attractive option for a wide range of precision op a...

Expanding on the company’s popular integrated SWIFT family of DC/DC converters, Texas Instruments Incorporated (TI) introduced today a new 65-V input, 1.5-A output step-down switcher with integrated FET that achieves significant energy savings in light-load efficiency. The wide-input converter helps saves up to 25 percent of board space compared to competitive wide-input voltage solutions and eases design in industrial and automotive applic...

Continuing to push the limits of data converter performance, Texas Instruments Incorporated today introduced the industry’s fastest 16-bit digital-to-analog converter (DAC). The quad DAC34SH84 is 50-percent faster and uses 50-percent less power than the closest 16-bit DAC alternative, clocking in at 1.5 GSPS and consuming just 362 mW per channel.

Texas Instruments has introduced six new digital-to-analog converters (DACs) available in 12-, 14- and 16-bit versions and with either SPI or parallel interface. The eight-channel DAC87x8 family features a typical power consumption in normal mode of 14.8 mW/channel, dropping to

Texas Instruments has introduced a family of 16-, 14- and 12-bit simultaneous sampling successive approximation register (SAR) analog-to-digital converters (ADCs) with high-voltage inputs. The ADS8556, ADS8557 and ADS8558 offer a sampling range of 730 kSPS and signal-to-noise ratio (SNR) up to 91.5 dB, and include the industry’s only simultaneous sampling ADC that offers true, 16-bit no missing codes (NMC) performance.

Texas Instruments has introduced a family of six-channel power management ICs for single-cell, lithium-powered portable electronics. Combining high-performance power building blocks in a single 4 mm x 4 mm package, the easy-to-design devices support power system requirements of advanced application processors used in smart phones, portable media players, navigation systems and other electronics.

Texas Instruments has introduced two 14- and 12-bit, 210-MSPS analog-to-digital converters (ADCs) to its pin-compatible, high-speed ADS5546 family. The ADS5547 and ADS5527 provide the highest performance at 210 MSPS with up to 73.3-dBFS signal-to-noise ratio (SNR) and 85-dBc spurious-free dynamic range (SFDR) at 70 MHz input frequency .
