The TLV2721IDBVT is an amplifier from the “low current” family of products from Texas Instruments. It is a low cost, low power, and low noise model that is suited for precision instrumentation, industrial sensor amplifiers, active filters, and medical diagnostic applications. This amplifier not only provides excellent noise performance and stability but also provides a low slew rate of 0.25V/μs, low noise of ±0.15pA/°C offset, low power consumption, and low offset of <±0.25mV. It operates from ±2V to ±16V power supplies and has a single ended output range from -1V to +1V.

The TLV2721IDBVT is a rail-to-rail CMOS instrumentation amplifier (IA) with a low 1/f noise corner of 200 Hz and a maximum 1/f noise corner of 1 MHz. It features an input bias current of < 2 nA, a gain drift of 0.1ppm/°C and a low 3 mV slew rate. It has an input voltage noise of 0.6 nV/√Hz and an output noise of 20 μVrms. This amplifier also has a high common-mode gain of 110 dB and a wide common-mode (CM) input voltage range of ±2V to ±16V. Additionally, it has an extremely low output impedance of 0.001 ohms. The amplifier has an uncommitted unity-gain non-inverting input and an uncommitted unity-gain inverting input. It also has an uncommitted unity-gain non-inverting output and an uncommitted unity-gain inverting output.

In terms of its working principle, the TLV2721IDBVT amplifier features a low voltage CMOS transimpedance structure with an active feedback path. This allows for excellent performance, low power consumption, and ease of copy exact design. This amplifier is a single-supply instrumentation amplifier with integrated drivers for the unity gain current-to-voltage conversion. It takes the analog input voltage range of ±2V to ±16V and amplifies it using a low impedance CMOS transimpedance amplifier with an active feedback path. This transimpedance amplifier has an input impedance of 0.001 ohms and a wide CM range of ±2V to ±16V. It converts the measured analog current to a low voltage signal through the built-in transimpedance converter. The output voltage range is adjustable with a range of -1V to +1V. As the amplifier is designed with internal feedback circuitry, it has a low output impedance of 0.01 Ω.
