Mouser Electronics Now Stocking Industry’s Lowest-Power Zero-Drift Instrumentation Amplifier from TI

Mouser Electronics, Inc., known for its rapid introduction of the newest products, today announced it is stocking the industry’s lowest-power zero-drift instrumentation amplifier from Texas Instruments Inc. (TI).

“In keeping with our goal to be engineers’ go-to source for the newest TI product introductions, Mouser is continuously adding new TI devices to our portfolio,” said Mike Scott, Mouser Vice President of Active Products. “The industry-leading INA333 instrumentation amplifier is just one of the new TI products we have in stock and available for purchase.”

The INA333 features the lowest quiescent current and lowest input bias current, as well as an impressive power-to-noise ratio, very low offset voltage/drift, and 1.8V operation. The device improves accuracy and stability while extending battery life in a variety of precision, low-power applications such as portable medical, handheld instrumentation, weigh scales, and data acquisition.

Utilizing TI’s zero-drift technology that eliminates chopping noise and provides very low input noise, the INA333 features a versatile three op amp architecture to simplify design and reduce board space. Special filters decrease radio frequency interference and dramatically reduce susceptibility to RF-induced offset voltage variations.

With only 75uA of quiescent current and operation on power supplies as low as 1.8V, the INA333 maximizes power efficiency. Low offset voltage of 25uV and offset drift of 0.1uV/C deliver excellent accuracy and long-term stability. Applications with high impedance sources benefit from the device’s low input bias current of 200pA.

Mouser Electronics Now Stocking TriQuint-WJ’s New WJA Family Gain Block Amplifiers for Broadband Applications

Mouser Electronics, Inc., known for its rapid introduction of the newest products, today announced it is now stocking WJ Communication’s WJA1001 and WJA1021 – the latest additions to their +5V Active Bias General Purpose Gain Block amplifier series. WJ Communications, Inc, recently acquired by TriQuint Semiconductor, is a leading supplier of radio frequency (RF) products and solutions for the wireless infrastructure and radio frequency identification (RFID) reader markets.

The WJA high-performance broadband amplifiers provide an excellent mix of power gain, linearity, and supply current performance in a SOT-89 package, enabling designers to integrate with their designs. The devices are internally matched to 50 ohm and only require DC-blocking/bypass capacitors and a bias inductor for operation. The amplifiers utilize the high-reliability InGaP/GaAs HBT process technology and are suitable for current and next generation wireless applications such as GSM, PCS, CDMA, W-CDMA, WiBro and WiMax, Repeaters, BTS Transceivers, and RFID.

The WJA1001 has been optimized to offer industry-leading linearity performance and provides 19dB gain at 900MHz, a +20dBm 1-dB compression point, and +45dBm OIP3 at 900MHz, while drawing only 100mA of current from a 5V supply voltage.

The WJA1021 gain block amplifier offers +37.5dBm OIP3 at 1.9GHz and is ideal for high linearity applications in the 50 to 4000MHz frequency range. At 1.9GHz, the device typically provides 17.5dB gain, +37.5dBm OIP3, and19dBm P1dB, drawing only 90mA current from a 5V supply.

“Having the newest products on the shelf at Mouser allows our engineering customers to design with the latest technologies,” said Mike Scott, Mouser’s Vice President of Active Products. “RF system designers consistently need products with improved linearity and other electrical and physical characteristics like these gain blocks from TriQuint-WJ.”
