3 Description
The INA1650-Q1 SoundPlus™ audio line receiver
achieves an extremely high common-mode rejection
ratio (CMRR) of 91 dB while maintaining ultra-low
THD+N of –120 dB at 1 kHz for 22-dBu signal levels.
Unlike other line receiver products, the INA1650-Q1
CMRR is characterized over temperature and tested
in production to deliver consistent performance in a
wide variety of applications.
The INA1650-Q1 operates over a very-wide-supply
range of ±2.25 V to ±18 V, on 10.5 mA of supply
current. In addition to the two line-receiver channels,
a buffered midsupply reference output is included to
allow the INA1650-Q1 to be configured for dual- or
single-supply applications. The mid-supply output can
be used as a bias voltage for other analog circuitry in
the signal chain.
The INA1650-Q1 features a unique internal layout for
lowest crosstalk and freedom from interactions
between channels, even when overdriven or
overloaded. This device is specified from –40°C to
+125°C.
