Low Noise Preamplifiers

THAT low noise preamplifiers are high performance current-feedback instrumentation amplifiers designed for low source-impedance preamp and bus summing applications. The ICs are available in a variety of packages and pin configurations, making some models pin compatible with the Analog Devices and the Texas Instruments devices. The parts are designed from the ground up in THAT’s complementary dielectric isolation process and include on-chip laser-trimmed Si-Chrome thin film resistor.
In microphone preamplifier applications THAT ICs improve on previous integrated designs by offering lower noise at low gains, wider bandwidth, higher slew rate, lower distortion, and lower supply current. Additionally we offer programmable controllers which when paired with our 1580 or 1583 preamplifier enables digitally controlled microphone preamplifiers with unprecedented performance.
