THS4541QRGTRQ1

The THS4541-Q1 device is a low-power, voltage-feedback, fully differential amplifier (FDA) with an input common-mode range below the negative supply rail and rail-to-rail outputs. It is designed for low-power data acquisition systems where high density is critical for high-performance ADC or DAC interface designs. The THS4541-Q1 device provides the negative-rail inputs required to connect DC-coupled, center-grounded source signals. These negative-rail inputs, combined with rail-to-rail outputs, make it easy to connect single-ended, ground-referenced bipolar signal sources to various successive approximation register (SAR), Δ-Σ, or pipelined ADCs using only a single 2.7V to 5.4V supply. The THS4541-Q1 device is specified for operation from -40°C to +125°C and is available in a 16-pin, very thin quad flat no-lead (VQFN) package.
