1. 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 implied.
2. Input terminals are diode-clamped to the power-supply rails. Input signals that can swing
more than 0.5V beyond the supply rails should be current-limited to 10mA or less.
ESD SENSITIVITY CAUTION
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

OPERATION INSTRUCTION
APPLICATION NOTES
The CBM8511, CBM8512, CBM8513, CBM8514
series op amps are unity-gain stable and free from
unexpected output phase reversal. They use
auto-zeroing techniques to provide low offset voltage
and very low drift over time and temperature.
independent of the positive supply voltage. A valid
logic low is defined as < 0.8V above the V– supply pin.
If dual or split power supplies are used, be sure that
logic input signals are properly referred to the
negative supply voltage. The Enable pin must be
connected to a valid high or low voltage, or driven,
not left open circuit.
Good layout practice mandates use of
a 0.1μF
capacitor placed closely across the supply pins.
For lowest offset voltage and precision performance,
circuit layout and mechanical conditions should be
optimized. Avoid temperature gradients that create
thermoelectric (Seebeck) effects in thermocouple
junctions formed from connecting dissimilar
conductors. These thermally-generated potentials
can be made to cancel by assuring that they are equal
on both input terminals.
The logic input is a high-impedance CMOS input,
with separate logic inputs provided on the dual
version. For batteryoperated applications, this feature
can be used to greatly reduce the average current and
extend battery life.
The enable time includes one full autozero cycle
required by the amplifier to return to VOS accuracy.
Prior to this time, the amplifier functions properly, but
with unspecified offset voltage.
Use low thermoelectric-coefficient connections
(avoid dissimilar metals).
Disable time is 1μs. When disabled, the output
assumes a high-impedance state. This allows the
CBM8513 to be operated as a gated amplifier, or to
have the output multiplexed onto a common analog
output bus.
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 will reduce the likelihood
of junctions being at different temperatures, which
can cause thermoelectric voltages of 0.1μV/°C or
higher, depending on materials used.
LAYOUT GUIDELINES
Attention to good layout practices is always
recommended. Keep traces short. When possible, use
a 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
OPERATING VOLTAGE
The CBM8511, CBM8512, CBM8513, CBM8514
series op amps operate over a power-supply range of
+2.5V to +5.5V (±1.25V to ±2.75V). Supply voltages
higher than 7V (absolute maximum) can permanently
damage the amplifier. Parameters that vary over
supply voltage or temperature are shown in the
Typical Characteristics section of this data sheet.

EMI
(electromagnetic-interference) susceptibility
CBM8513 ENABLE FUNCTION
The enable/shutdown digital input is referenced
to the V– supply voltage of the amp. A logic high
enables the op amp. A valid logic high is defined as >
75% of the total supply voltage. The valid logic high
signal can be up to 5.5V above the negative supply,
