8.1 Overview
The OPA1662-Q1 operational amplifier achieves a low 3.3 nV/√Hz noise density with an ultra-low distortion of
0.00006% at 1 kHz that makes the device suitable for audio application. This device has a wide supply range
with excellent PSRR, making it a suitable option for applications that are battery powered without regulation.

8.3 Feature Description
8.3.1 Operating Voltage
The OPA1662-Q1 op amp operates from ±1.5-V to ±18-V supplies while maintaining excellent performance. The
OPA1662-Q1 can operate with as little as 3 V between the supplies and up to 36 V between the supplies.
However, some applications do not require equal positive and negative output voltage swing. With the
OPA1662‑Q1 device, power-supply voltages do not need to be equal. For example, the positive supply could be
set to 25 V with the negative supply at –5 V.
In all cases, the common-mode voltage must be maintained within the specified range. In addition, key
parameters are assured over the specified temperature of T_A = –40°C to 85°C. Parameters that vary significantly
with operating voltage or temperature are shown in the Typical Characteristics.
