OPA330 OPA2330 OPA4330 SBOS432E – AUGUST 2008 – REVISED FEBRUARY 2011 www.ti.com APPLICATIONS INFORMATION The OPA330, OPA2330, and OPA4330 are unity-gain stable, precision operational amplifiers free from unexpected output and phase reversal. The use of proprietary Zerø-Drift circuitry gives the benefit of low input offset voltage over time and temperature, as well as lowering the 1/f noise component.

OPA330 OPA2330 OPA4330 SBOS432E – AUGUST 2008 – REVISED FEBRUARY 2011 www.ti.com ACHIEVING OUTPUT SWING TO THE OP AMP NEGATIVE RAIL Some applications require output voltage swings from 0V to a positive full-scale voltage (such as +2.5V) with excellent accuracy. With most single-supply op amps, problems arise when the output signal approaches 0V, near the lower output swing limit of a single-supply op amp. A good single-supply op amp may swing close to single-supply ground, but will not reach ground.

OPA330 OPA2330 OPA4330 SBOS432E – AUGUST 2008 – REVISED FEBRUARY 2011 RN are operational resistors used to isolate the ADS1100 from the noise of the digital I2C bus. Because the ADS1100 is a 16-bit converter, a precise reference is essential for maximum accuracy. If absolute accuracy is not required, and the 5V power supply is sufficiently stable, the REF3130 may be omitted.
