. The AD621BR-REEL is an ideal choice for designers looking for a low-cost, low-power op-amp with high performance. Due to its design and low power consumption, the AD621BR-REEL is also suitable for battery operated applications.

The AD621BR-REEL has many other applications, from digital-to-analog and analog-to-digital converters to instrumentation amplifiers for single or multi-channel data acquisition. The AD621BR-REEL can also be used as a voltage-controlled amplifier for high-gain applications, such as in modulators or demodulators.

Working Principle

The AD621BR-REEL is a low power, bipolar op-amp featuring a differential input stage with a common-mode input range extending beyond the supply rail, high input impedance and a wide range of small-signal bandwidths. The AD621BR-REEL is a single supply device, accepting either ±5 V or single-ended +5 V and switching between the two via a switchable pin.

The AD621BR-REEL has a high gain bandwidth product, making it suitable for both high frequency and low frequency applications. The op-amp also maintains excellent linearity in both the input and output stages, which is key for applications such as signal process and data acquisition.

The op-amp also has a wide common-mode input range extending from 0 V to 5.5 V, which is perfect for single-supply operation, the op-amp having no latch-up tendencies. The op-amp also boasts high slew rate and low distortion across the frequency range.

The AD621BR-REEL is also offered in a die form, allowing for optimum integration and thus providing customers with a more cost-effective solution.
