The OPA1662-Q1 is a dual, bipolar-input operational amplifier which is well suited for premium audio external amplifier applications in infotainment and cluster systems. In audio systems, the main concern is to ensure a clear, quality output signal which means minimuzing any noise introduced to the signal. The OPA1662-Q1 offers low noise density with an ultra-low distortion of 0.00006% at 1 kHz that maximizes the signal output. Additionally, this op amp offers rail-to-rail output swing to within 600 mV with 2-kΩ load. The wide headroom ensures that the output signal does not clip, and therefore preserves the audio quality.
The OPA1662-Q1 operates 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 wide supply range enables design flexibility for the device as it can be integrated from a power amplifier driven by the battery to being driven from an ADC to DAC for low-power applications. Additionally, this device also has a high-output drive capability of ±30 mA and can act as the sole audio amplifier for low-power applications, such as for cluster chimes.
The device also features completely independent circuitry for each of the two channels to enable low crosstalk and freedom from interactions between each channel, even when overdriven or overloaded. This feature enables customers to drive two different audio signals with ease of mind that the signals are not affected by each other.
The OPA1662-Q1 offers a wide bandwidth of 22 MHz and high slew rate of 17 V/µs which is applicable as a high and low side sensing for ripple currents in SMPS devices or motor drives. As a current sensor, the OPA1662-Q1 can be used as peak current mode control, with the op amps offering stability and enabling higher bandwidth for the system. The OPA1662-Q1 is applicable in body control modules and HEV or EV converters where motors typically are used.
