DESCRIPTION
•
•
The OPA317 series of CMOS operational amplifiers
offer precision performance at a very competitive
price. These devices are members of the Zerø-Drift
family of amplifiers that use a proprietary
autocalibration technique to simultaneously provide
low offset voltage (90 μV max) and near-zero drift
over time and temperature at only 35 μA (max) of
quiescent current.

The OPA317 family features rail-to-rail input and
output in addition to near flat 1/f noise, making this
amplifier ideal for many applications, and much easier
to design into a system. These devices are optimized
for low-voltage operation as low as +1.8 V (±0.9 V)
and up to +5.5 V (±2.75 V).
The OPA317 (single version) is available in the
SC70-5, SOT23-5, and SOIC-8 packages. The
OPA2317 (dual version) is offered in MSOP-8 and
SOIC-8 packages. The OPA4317 is offered in the
standard SOIC-14 and TSSOP-14 packages, as well
as in the space-saving VQFN-14 package. All
versions are specified for operation from –40°C to
+125°C.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not supported.
Input terminals are diode-clamped to the power-supply rails. Input signals that can swing more than 0.3 V beyond the supply rails should
be current limited to 10 mA or less.

SBOS682A – MAY 2013 – REVISED JUNE 2013
APPLICATIONS INFORMATION
The OPA317, OPA2317, and OPA4317 are unity-gain stable, precision operational amplifiers free from
unexpected output and phase reversal. 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. As a result of the high PSRR, these
devices work well in applications that run directly from battery power without regulation. The OPA317 family is
optimized for low-voltage, single-supply operation. These miniature, high-precision, low quiescent current
amplifiers offer high-impedance inputs that have a common-mode range 100 mV beyond the supplies, and a railto-rail output that swings within 100 mV of the supplies under normal test conditions. The OPA317 series are
precision amplifiers for cost-sensitive applications.
OPERATING VOLTAGE
The OPA317 series op amps can be used with single or dual supplies from an operating range of VS = +1.8 V
(±0.9 V) up to +5.5 V (±2.75 V).
CAUTION
Supply voltages greater than +7 V can permanently damage the device.
See the Absolute Maximum Ratings table. Key parameters that vary over the supply voltage or temperature
range are shown in the Typical Characteristics section of this data sheet.
INPUT VOLTAGE
The OPA317, OPA2317, and OPA4317 input common-mode voltage range extends 0.1 V beyond the supply
rails. The OPA317 is designed to cover the full range without the troublesome transition region found in some
other rail-to-rail amplifiers.
Typically, input bias current is about 200 pA; however, input voltages exceeding the power supplies can cause
excessive current to flow into or out of the input pins. Momentary voltages greater than the power supply can be
tolerated if the input current is limited to 10 mA. This limitation is easily accomplished with an input resistor, as
shown in Figure 18.

Figure 18. Input Current Protection
INPUT DIFFERENTIAL VOLTAGE
The typical input bias current of the OPA317 during normal operation is approximately 200 pA. In overdriven
conditions, the bias current can increase significantly (see Figure 17).The most common cause of an overdriven
condition occurs when the op amp is outside of the linear range of operation. When the output of the op amp is
driven to one of the supply rails, the feedback loop requirements cannot be satisfied and a differential input
voltage develops across the input pins. This differential input voltage results in activation of parasitic diodes
inside the front-end input chopping switches that combine with 10-kΩ electromagnetic interference (EMI) filter
resistors to create the equivalent circuit shown in Figure 19. Note that the input bias current remains within
specification within the linear region.

INTERNAL OFFSET CORRECTION
The OPA317, OPA2317, and OPA4317 op amps use an auto-calibration technique with a time-continuous, 125kHz op amp in the signal path. This amplifier is zero-corrected every 8 μs using a proprietary technique. Upon
power-up, the amplifier requires approximately 100 μs to achieve specified VOS accuracy. This design has no
aliasing or flicker noise.
EMI SUSCEPTIBILITY AND INPUT FILTERING
Operational amplifiers vary in their susceptibility to EMI. If conducted EMI enters the operational amplifier, the dc
offset observed at the amplifier output may shift from its nominal value while the EMI is present. This shift is a
result of signal rectification associated with the internal semiconductor junctions. While all operational amplifier
pin functions can be affected by EMI, the input pins are likely to be the most susceptible. The OPA317
operational amplifier family incorporates an internal input low-pass filter that reduces the amplifier response to
EMI. Both common-mode and differential mode filtering are provided by the input filter. The filter is designed for a
cutoff frequency of approximately 8 MHz (–3 dB), with a roll-off of 20 dB per decade.
ACHIEVING OUTPUT SWING TO THE OP AMP NEGATIVE RAIL
Some applications require output voltage swings from 0 V to a positive full-scale voltage (such as +2.5 V) with
excellent accuracy. With most single-supply op amps, problems arise when the output signal approaches 0 V,
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. The output of the OPA317, OPA2317, and OPA4317 can be
made to swing to ground, or slightly below, on a single-supply power source. To do so requires the use of
another resistor and an additional, more negative power supply than the op amp negative supply. A pull-down
resistor can be connected between the output and the additional negative supply to pull the output down below
the value that the output would otherwise achieve, as shown in Figure 20.

Figure 20. For VOUT Range to Ground
The OPA317, OPA2317, and OPA4317 have an output stage that allows the output voltage to be pulled to its
negative supply rail, or slightly below, using the technique previously described. This technique only works with
some types of output stages. The OPA317, OPA2317, and OPA4317 have been characterized to perform with
this technique; the recommended resistor value is approximately 20 kΩ. Note that this configuration increases
the current consumption by several hundreds of microamps. Accuracy is excellent down to 0 V and as low as –2
mV. Limiting and nonlinearity occurs below –2 mV, but excellent accuracy returns as the output drives back up
above –2 mV. Lowering the resistance of the pull-down resistor allows the op amp to swing even further below
the negative rail. Use resistances as low as 10 kΩ to achieve excellent accuracy down to –10 mV.

RN are operational resistors used to isolate the ADS1100 from the noise of the digital I2C bus. The ADS1100 is a
16-bit converter; therefore, a precise reference is essential for maximum accuracy. If absolute accuracy is not
required and the 5-V power supply is sufficiently stable, the REF3130 may be omitted.

GENERAL LAYOUT GUIDELINES
Attention to good layout practice is always recommended. Keep traces short and, when possible, use a printed
circuit board (PCB) ground plane with surface-mount components placed as close to the device pins as possible.
Place a 0.1-μF capacitor closely across the supply pins. Apply these guidelines throughout the analog circuit to
improve performance and provide benefits, such as reducing the electromagnetic interference (EMI)
susceptibility.
Optimize circuit layout and mechanical conditions for lowest offset voltage and precision performance. Avoid
temperature gradients that create thermoelectric (Seebeck) effects in the thermocouple junctions formed from
connecting dissimilar conductors. These thermally-generated potentials can be made to cancel by assuring they
are equal on both input terminals. Other layout and design considerations include:
• Use low thermoelectric-coefficient conditions (avoid dissimilar metals).
• Thermally isolate components from power supplies or other heat sources.
• Shield op amp and input circuitry from air currents, such as cooling fans.
Following these guidelines reduces the likelihood of junctions being at different temperatures, which can cause
thermoelectric voltages of 0.1 μV/°C or higher, depending on the materials used.
