Micropower op amps
provide 1MHz bandwidth
Texas Instruments has a new family of micropower op amps featuring an impressive speed/power ratio of 1MHz bandwidth at 45uA supply current
The OPA348 family is aimed at a wide variety of applications including portable and battery-operated equipment, medical instrumentation, automotive and general-purpose applications. 'By offering 1MHz bandwidth at only 45uA supply current, we have hit the sweet spot of designers' speed/power requirements', said Tadija Janjic, strategic marketing engineer of TI's high-performance amplifier products.

Webcast to address wireless power optimisation
Texas Instruments and Avnet Electronics Marketing will present a live Analog eLab webcast on 'Optimising power in low-power wireless systems' on 12th April 2006
'The unequalled combination of excellent AC and DC performance, rail-to-rail operation, micropackage options and a low price will establish the OPA348 as the perfect low-power op amp for every analogue designer's high-performance toolbox'.
The OPA348 is optimised for single 2.1 to 5.5V supplies, guaranteeing superior performance even in low battery situations.
Low supply current (45uA) and low input bias current (0.5pA) make the OPA348 ideal for low-power, high-impedance devices such as CO detectors and other sensor applications.
The input common-mode voltage range extends 200mV beyond the power supply rails and the output swings to within 25mV of the rails.
Other features include 108dB open-loop gain and 1mV input offset voltage.
The extended temperature range of -40 to +125C over all supply voltages offers additional design flexibility.
The OPA348 (single) is available in SOT23-5 and SO-8 packages and suggested resale pricing starts at $0.49 in 1000 piece quantities.
The OPA4348 (quad) is packaged in a TSSOP-14 and SO-14 with suggested resale pricing starting at $1.05 in 1000 piece quantities.
The dual OPA2348, scheduled to be available in Q1 2002, will be packaged in SOT23-8 and SO-8 packages.
