TLV2264MJ - Quad Low-Power Rail-to-Rail Op Amp | Texas Instruments
MPN: TLV2264MJ ✓ פעילTLV2264MJ סקירה
An operational amplifier is an analog integrated circuit that uses high-gain differential feedback to amplify the difference between two input voltages. The TLV2264 belongs to the broader hierarchy of amplifier IC, operational amplifier, low-voltage CMOS amplifier, and low-power signal-conditioning IC. Its LinCMOS architecture combines rail-to-rail output operation with low supply current, making it useful where the input and output must operate close to the available supply rails.
The TLV2264MJ includes four amplifiers in one package. Key characteristics include a 2.7 V to 8 V supply range, 12 nV/√Hz typical noise density at 1 kHz, 2 µV/°C input voltage drift, 550 V/µs slew rate, and 800 µA typical supply current. Its output swing extends to both supply rails, allowing greater usable output range than a conventional non-rail-to-rail amplifier at low supply voltages.
The low input bias current of 60 pA helps preserve measurement accuracy with high-impedance sensors. Combined with low noise density, it supports precision current measurement, bridge excitation, transducer amplification, and low-frequency precision filtering. The 550 V/µs slew rate also supports moderate-bandwidth signal conditioning where fast output transitions are needed without moving to a high-power amplifier family.
Typical applications include battery-powered sensor interfaces, portable medical-instrument signal paths, industrial process measurement, current-loop receivers, low-level data acquisition, analog filtering, and general-purpose amplifier stages. The 14-pin CDIP package also provides a practical choice for rugged through-hole assemblies and military-temperature equipment when soldering and mechanical robustness are priorities.
Designers should maintain sufficient supply-headroom for stable operation and account for input and output common-mode limits when signals approach either rail. Decoupling capacitors should be placed close to the supply pins, and sensitive inputs should be protected from leakage, contamination, and ESD. Because the part contains four amplifiers, unused sections should be configured according to the manufacturer’s recommended stable-input method rather than left floating.
This product guide combines the device’s principal electrical and environmental characteristics with practical application guidance, pin-level integration information, and a transparent comparison framework. It is intended to help engineers evaluate the TLV2264MJ for military-temperature, low-noise, low-power analog designs before committing to a CDIP-14 layout.

יישומים טיפוסיים

High-Impedance Sensor Signal Conditioning
The TLV2264MJ fits high-impedance sensor front ends because its 60 pA typical input bias current limits the error introduced by sensor leakage and source resistance, while its 12 nV/√Hz typical noise density at 1 kHz supports low-level signal measurement. Place one amplifier in a non-inverting or differential configuration close to the sensor connector, and route the input as a short, guarded trace. Its 2.7 V to 8 V supply range fits compact 3.3 V or 5 V acquisition systems. The 550 V/µs slew rate provides useful bandwidth for sensors with moderate signal slopes, although settling time and total input capacitance must be checked before selecting the gain.
Portable Battery-Powered Instrumentation
The TLV2264MJ is suitable for portable instrumentation that must process signals from a small supply because the device operates from 2.7 V to 8 V and draws 800 µA typical supply current. Four amplifiers in one 14-pin CDIP can provide conditioning for multiple low-frequency channels without requiring four separate packages. Its rail-to-rail output uses more of the available output range, helping preserve signal amplitude in compact systems. Designers should budget power across all four channels, confirm whether the chosen configuration leaves any amplifier unused, and apply the manufacturer’s stable-input method to unused sections.
Precision Current-Measuring Front End
The TLV2264MJ can support precision current-measurement circuits where the shunt voltage is small and the source impedance may be high. Its low 60 pA typical input bias current reduces unintended current through the sensing network, and the 12 nV/√Hz typical noise density helps preserve weak shunt signals. A transimpedance or differential arrangement should place the amplifier close to the shunt to minimize sensitive-trace area. The 550 V/µs slew rate must be checked against the fastest expected current transient, while the 2.7 V to 8 V operating range supports both low-voltage and higher-voltage analog systems.
Industrial Process Measurement
The TLV2264MJ is appropriate for industrial process-measurement front ends that operate from low-voltage rails and require low-noise, low-bias amplification. Its 12 nV/√Hz typical noise density, 60 pA typical input bias current, and 950 µV input offset-voltage specification provide useful baseline parameters for slow sensor signals. The -55 °C to +125 °C operating range supports harsh industrial environments, while the CDIP-14 package allows conventional through-hole assembly. Input protection, isolation boundaries, grounding, and filtering should be designed around the specific transducer because amplifier specifications alone do not suppress external interference.
Low-Frequency Precision Filtering
The TLV2264MJ can implement low-frequency precision filter stages because its low noise and low input bias current reduce errors in high-impedance active-filter networks. Four channels provide flexibility for cascaded low-pass, high-pass, or buffering stages within a 2.7 V to 8 V system. The 550 V/µs slew rate gives the amplifier useful dynamic range for moderate-frequency signals, while the rail-to-rail output expands usable signal swing. Component tolerances and capacitor leakage can dominate final accuracy, so use stable resistor and capacitor selections and verify the complete filter response rather than relying on amplifier specifications alone.
Military-Temperature Through-Hole Control Systems
The TLV2264MJ is suited to military-temperature through-hole control and measurement systems because its specified operating range is -55 °C to +125 °C and it uses a 14-pin military-grade CDIP package. Its low-power CMOS architecture, 800 µA typical supply current, and low-noise input stage suit embedded analog channels operating from 2.7 V to 8 V. The ceramic DIP construction also avoids relying solely on a small-area surface-mount footprint. System-level qualification remains the designer’s responsibility, including power-budget analysis, grounding, protection against conducted and radiated interference, and verification of critical parameters over temperature.

הערות תכנון
Place the supply-decoupling capacitor close to the V+ and V- pins, and keep the loop between the capacitor, device, and power return as small as practical. Sensitive amplifier inputs should be short and routed away from switching nodes and high-current return paths. On a CDIP board, use through-hole leads to provide the mechanical strength expected in rugged assemblies, but still minimize exposed sensitive-trace length to reduce leakage and pickup.
Do not leave unused amplifier inputs floating. Configure each unused section with a feedback arrangement that keeps the amplifier stable, following the manufacturer’s recommended method. Also check the input common-mode range for every operating point rather than assuming that rail-to-rail output automatically means unrestricted rail-to-rail input. In battery-powered or precision systems, confirm that ground offsets and input bias error remain acceptable at the highest source impedance.
The 550 V/µs slew rate is useful for moderate-bandwidth signals, but a fast output edge can increase capacitive-load sensitivity and electromagnetic emissions. Keep feedback traces short, use direct signal routing, and add isolation resistance at connector inputs where leakage matters. Evaluate the complete channel with realistic source capacitance, cable capacitance, sensor impedance, and filter components because the 12 nV/√Hz noise-density figure alone does not determine total output noise.
מידע על תאימות
The part is identified as a military-grade operational amplifier, but no specific RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations were found in the available product records. AEC-Q100 is not applicable because this is an operational amplifier rather than an automotive-qualified integrated circuit.
