3 Description
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.
