SN75DP128ARTQR is a member of Texas Instruments’ FET-Input Operational Amplifiers With Shutdown (Op Amps) family of devices. This device is a high-speed, low-power amplifier that provides rail-to-rail input and output performance. It is ideal for battery-powered applications and other low-voltage designs.

The SN75DP128ARTQR features a low-offset voltage, low power consumption, 1.6MHz unity gain bandwidth and a wide supply range. The device also includes an on-chip shutdown mode, which enables power savings when the amplifier is not in operation. Other features include low-noise performance, high gain slewing rate, wide input common-mode range, and wide supply swing.

The SN75DP128ARTQR is typically used in various consumer and automotive applications such as automotive and industrial power-supply monitors, battery-charger applications, and industrial instrumentation. It can also be used for low-power audio and low-power oscillation. With its low power consumption and wide bandwidth, the device provides an excellent performance in low-voltage battery-powered applications.

The SN75DP128ARTQR Op Amp has a flexible supply voltage, which allows a wide range of operating voltage from 1.8 V to 5.5V. The device consumes between 2.6mW and 11mW in delivering output currents up to 20mA. The operating temperature range is -40°C to 125°C and the supply line rejection ratio is 120 dB. Furthermore, the SN75DP128ARTQR features a 1.6MHz unity gain bandwidth, 18 V/ms slew rate, 13 μs settling time, and 65 dB of DC open-loop gain.

The working principle of the SN75DP128ARTQR is similar to that of other op amps: it amplifies the differences between its input terminals. The amplified current is then available at the output terminals. The SN75DP128ARTQR is configured with a non-inverting input and an inverting input. This configuration is known as a non-inverting amplifier and it amplifies the differences between the input terminals without inverting their phase. This enables the device to deliver high-quality signals even at low power output.

The SN75DP128ARTQR also features an optional shutdown mode that allows the device to be inactive when idle. This feature reduces power usage and extends battery life in battery-powered applications. The device operates at a low-noise level and provides a high gain-bandwidth product, allowing it to deliver high quality audio output in low-power applications.

In summary, the SN75DP128ARTQR is an ideal solution for low-power and low-voltage applications, both in consumer and automotive applications. It features low-noise performance, a rail-to-rail input and output performance, and low power consumption. The device also has a wide supply range and a wide input common-mode range, making it suitable for various conditions. Moreover, it is also capable of providing high-quality audio output even at low power output. Its low-power consumption and high bandwidth make it ideal for battery-powered applications, making it the perfect choice for various applications.
