Texas Instruments [India] Pvt. Ltd. Supplies 70-MHz High-Speed Programmable-Gain Amplifiers. Texas Instruments [India] Pvt. Ltd. Offers assorted range of s amplifiers, linear amplifiers, semiconductors, clocks, timers, microcontrollers, data converters, etc. The 70-MHz High-Speed Programmable-Gain Amplifiers of model numbers THS7001 [single] and THS7002 [dual] are high-speed programmable-gain amplifiers, ideal for applications where load impedance can often vary. Each channel on this device consists of a separate low-noise input preamp and a programmable gain amplifier [PGA]. The preamp is a voltage-feedback amplifier offering a low 1.7-nV/Hz voltage noise with a 100-MHz [-3 dB] bandwidth. The output pin of the preamp is accessible so that filters can be easily added to the amplifier. The 3-bit digitally-controlled PGA provides a -22-dB to 20-dB attenuation/gain range with a 6-dB step resolution. In addition, the PGA provides both high and low output clamp protection to prevent the output signal from swinging outside the common-mode input range of an analog-to-digital converter.
