LOW NOISE 0.1Hz to 10Hz: 0.4µVPP
LOW OFFSET VOLTAGE: 15µV (typ)
QUIESCENT CURRENT: 100µA (typ)
OFFSET DRIFT: 0.1µV/°C (typ)
SINGLE-SUPPLY OPERATION
SUPPLY VOLTAGE: 1.8V to 5.5V

The OPA378 and OPA2378 represent a new
generation of micropower operational amplifiers.
Rail-to-rail input, low input offset voltage (50µV max),
low quiescent current (125µA max), and 900kHz
bandwidth make this part very attractive for
low-power precision applications. In addition, this part
has excellent PSRR, making it an outstanding choice
for applications that run directly from batteries without
regulation.

SBOS417 – JANUARY 2008
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 0.3V beyond the supply rails should
be current limited to 10mA or less.

APPLICATIONS INFORMATION

junctions being at different temperatures, which can
cause thermoelectric voltages of 0.1µV/°C or higher,
depending on materials used.

INTERNAL OFFSET CORRECTION
The OPA378 and OPA2378 op amps use an
auto-calibration technique with a time-continuous
350kHz op amp in the signal path. This amplifier is
zero-corrected every 3µs using a proprietary
technique. Upon power-up, the amplifier requires
approximately 100µs to achieve specified VOS
accuracy. This architecture has no aliasing or flicker
noise.
GENERAL LAYOUT GUIDELINES
OPERATING VOLTAGE
The OPA378 and OPA2378 op amps operate over a
power-supply range of +1.8V to +5.5V (±0.9V to
±2.75V). Supply voltages higher than +7V (absolute
maximum) can permanently damage the device.
Parameters that vary over supply voltage or
temperature are shown in the Typical Characteristics
section of this data sheet.
INPUT VOLTAGE
The OPA378 and OPA2378 input common-mode
voltage range extends 0.1V beyond the supply rails.
The OPA378 is designed to cover the full
common-mode range without the troublesome
transition region found in some other rail-to-rail
amplifiers.
Normally, input bias current is about 150pA; 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 10mA. This limitation is easily accomplished
with an input resistor, as shown in Figure 23.
Attention to good layout practices 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 0.1µF
capacitor closely across the supply pins. These
guidelines should be applied throughout the analog
circuit to improve performance and provide
benefits such as reducing the electromagnetic
interference (EMI) susceptibility.
Operational amplifiers vary in susceptibility to radio
frequency interference (RFI). RFI can generally be
identified as a variation in offset voltage or dc signal
levels with changes in the interfering RF signal. The
OPA378 has been specifically designed to minimize
susceptibility to RFI and demonstrates remarkably
low sensitivity compared to previous generation
devices. Despite this design, strong RF fields may
cause varying offset levels. If the amplifier cannot be
located away from sources of radiation, shielding may
be needed. Twisting wire input leads makes them
more resistant to RF fields.

PRODUCT PREVIEW
The OPA378 and OPA2378 are unity-gain stable and
free from unexpected output phase reversal. These
devices use a proprietary auto-calibration technique
to provide low offset voltage and very low drift over
time and temperature. For lowest offset voltage and
precision performance, circuit layout and mechanical
conditions should be optimized. 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.

the ADS1100 from the noise of the digital I2C™ bus.
Because the ADS1100 is a 16-bit converter, a precise

absolute accuracy is not required, and the 5V power

Figure 27 shows a high side current monitor. The
load current develops a drop across RSHUNT, and the
low (or load side, most negative side) of RSHUNT is
connected to the noninverting input of the op amp.
The op amp feedback forces a replica of this voltage
on its inverting input, yielding a drop across RG that is
identical to the drop across RSHUNT. RG can be sized
to provide whatever current is most convenient to the
designer based on this voltage drop. The MOSFET
conveys this current out of its drain to ground, where
a resistor RL converts the current that flows through
RG and the MOSFET back into a voltage. In this way
RL/RG sets the voltage gain of this circuit. The op
amp is powered by the zener diode, which forms a
small power supply window of voltage. For the
OPA378, ±VS but must be between 1.8V and
5.5V.Two possible methods are shown to bias the
zener, the customary resistor bias and a current
mirror. To operate over at the lowest possible voltage
for the shunt supply, current mirror biasing could also
be used. In either case, note that the voltage at the
output terminal of this circuit is restricted by whatever
voltage is available at the shunt. Resistor R1 and the
diode on the noninverting input provide protection in
situations where the load might be shorted out. These
components clamp the noninverting input to within a
diode drop of the negative rail of the op amp under
short-circuit conditions.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and
package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS
compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
