3 Description
The OPA2320-Q1 device is a new generation of
precision low-voltage CMOS operational amplifiers
(op amps) optimized for very low noise and wide
bandwidth while operating on a low quiescent current
of only 1.45 mA.
The OPA2320-Q1 device is ideal for low-power,
single-supply applications. Low-noise (7 nV/vHz) and
high-speed operation also makes the device well-
suited for driving sampling analog-to-digital
converters (ADCs). Other applications include signal
conditioning and sensor amplification.
The OPA2320-Q1 device features a linear input stage
with zero-crossover distortion that delivers excellent
common-mode rejection ratio (CMRR) of 114 dB
(typical) over the full input range. The input common-
mode range extends 100 mV beyond the negative
and positive supply rails. The output voltage typically
swings within 10 mV of the rails.
In addition, the OPA2320-Q1 device has a wide
supply voltage range from 1.8 to 5.5 V with excellent
PSRR (106 dB) over the entire supply range, making
the device suitable for precision, low-power
applications that run directly from batteries without
regulation.
The OPA2320-Q1 device is available in an 8-pin
VSSOP (DGK) package.
