Differential amplifiers drive high-speed
ADCs
Three new high-performance low-distortion fully differential amplifiers drive high-speed ADCs in demanding test and measurement, medical imaging, wireless infrastructure and industrial applications.
Texas Instruments has made three additions to its high-performance family of low-noise low-distortion fully differential amplifiers that drive high-speed analogue-to-digital convertors (ADCs) in demanding applications such as test and measurement, medical imaging, wireless infrastructure and industrial applications Providing more flexibility to meet the needs of high-speed data acquisitions systems, the family allows designers to choose between high gain and unity gain stable, and between negative and mid-supply input common-mode voltages

Reference design for wireless optical comms
A new technology from Texas Instruments dramatically cuts the cost and complexity of bringing the high-speed datarates of optical networking to end users.
Designed for 3.3 to 5V data acquisition systems, the THS4511 and THS4513 unity gain stable versions, and the THS4508 amplifier are based on the previously announced THS4509.
The three new devices feature fully differential architecture and 5V single supply operation.
Depending on the device, bandwidths for the devices range from 1600 to 2000MHz with slew rates from 4900 to 6400V/us.
The amplifiers are also characterised for operation over the full industrial temperature range from -40 to +85C.
The THS4508/9/11/13 combine DC precision with exceptional noise and distortion performance.
When used along with a high-speed ADC like the ADS5424, 14bit 105Msample/s ADC, these features enable the designer to ensure accurate low-level signal measurements and high signal fidelity, while greatly simplifying the design process and reducing the overall solution size.
In addition, these amplifiers and data convertors interface well with the TMS320C6000TM DSP products in a high-performance signal chain for wideband applications.
The THS4513, THS4511 and THS4508 are available now from TI and its authorised distributors.
The devices are offered in 16-pin quad flat no-leads (QFN) packages, with 1000-off pricing ranging from $3.25 to $3.95.
