OPA2320-Q1 Precision, 20-MHz, 0.9-pA, Low-Noise, RRIO,  
CMOS Operational Amplifier  
1 Features  
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.

Qualified for Automotive Applications  
AEC-Q100 Qualified with the Following Results:  
Device Temperature Grade 1: –40°C to 125°C  
Ambient Operating Temperature Range  
Device HBM ESD Classification Level 2  
Device CDM ESD Classification Level C4B  
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-

analog-to-digital  
Low Offset Voltage: 150 µV (max)  
High CMRR: 114 dB  
converters (ADCs). Other applications include signal  
conditioning and sensor amplification.  
Rail-to-Rail I/O  
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.  
Low Input Bias Current: 0.9 pA (max)  
Low Noise: 7 nV/vHz at 10kHz  
Wide Bandwidth: 20 MHz  
Slew Rate: 10 V/µs  
Quiescent Current: 1.45 mA/ch  
Single-Supply Voltage Range: 1.8 to 5.5 V  
Unity-Gain Stable  
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.
