The AD8278 and AD8279 are general-purpose difference amplifiers intended for precision signal conditioning in power critical applications that require both high performance and low power. The AD8278 and AD8279 provide exceptional commonmode rejection ratio (80 dB) and high bandwidth while amplifying input signals that are well beyond the supply rails. The on-chip resistors are laser trimmed for excellent gain accuracy and high CMRR. They also have extremely low gain drift vs. temperature.
The common-mode range of the amplifier extends to almost triple the supply voltage (for G = ½), making the amplifer ideal for single-supply applications that require a high commonmode voltage range. The internal resistors and ESD circuitry at the inputs also provide overvoltage protection to the op amp. The AD8278 and AD8279 can be used as difference amplifiers with G = ½ or G = 2. They can also be connected in a high precision, single-ended configuration for non inverting and inverting gains of −½, −2, +3, +2, +1½, +1, or +½.
The AD8278 and AD8279 provide an integrated precision solution that has a smaller size, lower cost, and better performance than a discrete alternative.

Texas Instruments LM4871MM/NOPB
The LM4871MM/NOPB is a mono bridged Audio Power Amplifier capable of delivering 3W of continuous average power into a 3R load with less than 10% THD when powered by a 5V power supply. To conserve power in portable applications, the LM4871's micropower shutdown mode (IQ = 0.6µA, typical) is activated when VDD is applied to the shutdown pin. Boomer audio power amplifier is designed specifically to provide high power, high fidelity audio output. It requires few external components and operates on low supply voltages from 2.0 to 5.5V. Since the LM4871 does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is ideally suited for low-power portable systems that require minimum volume and weight. Additional LM4871 features include thermal shutdown protection, unity-gain stability and external gain set.
- No output coupling capacitors, bootstrap capacitors or snubber circuits are necessary
- Unity-gain stable
- External gain configuration capability

Texas Instruments TLV2465IN
The TLV246x is a family of low-power rail-to-rail input/output operational amplifiers specifically designed for portable applications. The input common-mode voltage range extends beyond the supply rails for maximum dynamic range in low-voltage systems. The amplifier output has rail-to-rail performance with high-output-drive capability, solving one of the limitations of older rail-to-rail input/output operational amplifiers. This rail-to-rail dynamic range and high output drive make the TLV246x ideal for buffering analog-to-digital converters.

Texas Instruments LM386N-1/NOPB
The LM386N-1/NOPB is a Wide Vin Class-D low Power Audio Amplifier with internal gain designed for use in low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 will increase the gain to any value from 20 to 200. The inputs are ground referenced while the output automatically biases to one-half the supply voltage. The quiescent power drain is only 24mW when operating from a 6V supply, making the LM386 ideal for battery operation.
