OPA1662AID vs OPA1662AIDR vs LMP2232AMAE/NOPB Comparison

The OPA1662AID is a dual bipolar-input Operational Amplifier with rail-to-rail output. The OPA1662 series of op amp offer rail-to-rail output swing to within 600mV with 2kR load, which increases headroom and maximizes dynamic range. This device also has a high output drive capability of ±30mA. The op amp is unity-gain stable and provide excellent dynamic behaviour over a wide range of load conditions. This device also features completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.

The OPA1662 (dual) and OPA1664 (quad) series of bipolar-input operational amplifiers achieve a low 3.3 nV/√Hz noise density with an ultralow distortion of 0.00006% at 1 kHz. The OPA1662 and OPA1664 series of op amps offer rail-to-rail output swing to within 600 mV with 2-kΩ load, which increases headroom and maximizes dynamic range. These devices also have a high output drive capability of ±30 mA. These devices operate over a very wide supply range of ±1.5 V to ±18 V, or +3 V to +36 V, on only 1.5 mA of supply current per channel. The OPA1662 and OPA1664 op amps are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions. These devices also feature completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded. The OPA1662 and OPA1664 are specified from –40°C to +85°C.

The LMP2232AMAE/NOPB is a dual MicroPower precision Operational Amplifier with CMOS input. It is designed for battery powered applications. The quiescent power consumption of only 26µW extends the battery life in portable systems. The LMP2232 is part of the LMP precision amplifier family. The high impedance CMOS input makes it ideal for instrumentation and other sensor interface applications. These precise specifications make the LMP2232 a great choice for maintaining system accuracy and long term stability. The LMP2232 has a rail-to-rail output that swings 15mV from the supply voltage, which increases system dynamic range. The common mode input voltage range extends 200mV below the negative supply, thus the LMP2232 is ideal for ground sensing in single supply applications.
