TLV2471AQDRG4Q1 is an integrated circuit from Texas Instruments that is typically used as a low-level amplifier or in applications that require a low-noise signal path. It is a monolithic linear Operational Amplifier (Op Amp). This device is designed for precision applications such as instrumentation amplifier applications and other linear signal processing where a differential input is necessary. It is also suitable for high-sensitivity, low-noise, low-power applications.

Overview of TLV2471AQDRG4Q1

The TLV2471AQDRG4Q1 includes several features, such as low supply current (1.2mA), wide common-mode range, rail-to-rail input/output and single-supply operation. It features an excellence signal-to-noise ratio of 70dB. The bandwidth is 1MHz and it has a low distortion of 0.0001%. The typical offset drift is 2uV/C and the minimum supply voltage is 4V. This IC comes in a compact QFN-10 package making it perfect for applications with space constraints

Application Field

The TLV2471AQDRG4Q1 makes an excellent choice for precision linear applications. It can be used as a low-noise instrumentation amplifier such as front-end amplifier for ECG, EEG and other biomedical applications. It can also be used for audio pre-amplifiers, GNSS receivers and other telecommunication applications. When combined with other components, it can be used in A/D converters, active filters, and precision circuit designs. The low-input bias current and low-offset voltage makes it ideal for applications requiring high accuracy and precision.

Working Principle

The TLV2471AQDRG4Q1 is a single-supply, low-power, monolithic linear Amplifier with wide band-width and high precision. It is a differential amplifier, which means it amplifies the difference in voltage between its two inputs. The two inputs of the amplifier are referred to as the non-inverting input (V+) and the inverting input (V-). The output voltage of the amplifier is a function of the difference between the non-inverting and inverting inputs and is determined by the following equation:

V_out = A × (V₊ - V_-)

Where A is the gain of the amplifier. The voltage gain of the amplifier is controlled by two external resistors, R₁ and R₂. By adjusting the resistance value of these two resistors, the amplifier can be configured to produce a gain anywhere from 1 to 10000.

The TLV2471AQDRG4Q1 amplifies the difference between V+ and V- and produces an output voltage in the range of -V_dd to +V_dd. The input range is also wide, spanning from -V_dd to + V_dd which means that the input signal can span the entire range of the supply voltage. This device also includes a slew-rate limiting feature, which allows it to produce high-speed signals with low distortion. This makes it perfect for audio and video applications, where low distortion and flat frequency response are essential.

Conclusion

The TLV2471AQDRG4Q1 is a low power, wide bandwidth, low-noise, monolithic linear amplifier from Texas Instruments. It is designed for precision applications such as instrumentation amplifier applications, active filters and A/D converters. It is also suitable for high-sensitivity, low-noise, low-power applications. It features an excellence signal-to-noise ratio of 70dB and can be configured for gains from 1 to 10000. It has a low distortion of 0.0001% and offers high-speed signals with low distortion.
