LT1007XH - Low-Noise 200°C Op Amp in TO-5 | Analog Devices
MPN: LT1007XH ✓ Hoạt độngLT1007XH Tóm tắt
An operational amplifier, or op amp, is a high-gain differential amplifier used to amplify, buffer, filter, compare, or control analog signals. The LT1007 belongs to the precision operational-amplifier hierarchy, where low input noise, low offset drift, high rejection, and stable operation are more important than maximum bandwidth or minimum cost. Its wide operating-temperature capability extends that precision-focused role to industrial, instrumentation, and high-temperature analog systems.
Key features include a 10 µV input offset voltage, 0.2 µV/°C input offset drift, and 130 dB common-mode rejection. The manufacturer describes a 2.5 nV/√Hz wideband noise density, a 2 Hz 1/f corner, and 60 nV peak-to-peak noise from 0.1 Hz to 10 Hz. The manufacturer datasheet also states that these devices are 100% tested at 200°C ±3°C, with normal operating-temperature specifications provided separately for the LT1007M version.
The LT1007 series was designed as a direct replacement for the OP-27 operational-amplifier family, as stated in the manufacturer datasheet. This heritage is important because it provides an established precision-amplifier upgrade path for existing instrumentation and signal-conditioning designs. The LT1007XH combines the series noise and precision characteristics with a hermetic TO-5 construction intended to support demanding thermal environments.
Typical uses include precision instrumentation, low-level sensor amplification, bridge and strain-gauge signal conditioning, laboratory measurement equipment, and industrial analog front ends. Its low-noise and low-drift characteristics are particularly valuable when the input signal is small and the useful measurement must remain stable despite temperature changes. In these applications, the amplifier is usually placed directly in front of an ADC or downstream measurement chain.
When designing with the LT1007XH, verify the exact LT1007XH electrical limits from the manufacturer datasheet rather than substituting the normal-temperature LT1007M limits. Decoupling, input-bias-current compensation, source impedance, output loading, and stability must be evaluated around the selected noise and gain conditions. The hermetic package also requires attention to lead strain, thermal expansion, and PCB soldering practices.
This page combines verified manufacturer specifications, current distributor sourcing information, same-package drop-in candidates, and practical selection guidance. It also distinguishes the uniquely tested LT1007XH temperature grade from ordinary package-code or reel-code variants, helping engineers make a replacement decision based on electrical compatibility and environmental requirements.

Ứng dụng tiêu biểu
LT1007XH phù hợp cho 6 Áp dụngs: Precision Instrumentation, Bridge and Strain-Gauge Signal Conditioning, High-Temperature Sensor Amplification, Low-Level Audio and Communication Interfaces, Laboratory Measurement Equipment, Industrial Analog Signal Conditioning.
Precision Instrumentation
The LT1007XH fits precision instrumentation where low-level differential signals must be amplified without adding excessive noise or temperature-dependent error. Its 2.5 nV/√Hz wideband input-noise density, 10 µV offset voltage, and 0.2 µV/°C offset drift establish a strong signal-to-error ratio for laboratory and industrial measurement systems. The 130 dB common-mode rejection and 130 dB power-supply rejection also help suppress interference coupled into sensitive inputs. It is especially useful when the amplifier operates near the high-temperature capability for which the LT1007X devices are 100% tested at 200°C ±3°C.
Được đề xuất
Bridge and Strain-Gauge Signal Conditioning
The LT1007XH is appropriate for bridge and strain-gauge front ends because small sensor signals require low voltage noise, low offset drift, and high common-mode rejection. The 60 nV peak-to-peak noise from 0.1 Hz to 10 Hz supports low-frequency measurement, while the 0.2 µV/°C drift limits temperature-related baseline movement. Its 130 dB common-mode rejection can reduce errors from common-mode voltage on the sensor lines. The amplifier should be evaluated with the actual bridge impedance, excitation method, cable length, and grounding configuration because those external factors materially affect total measurement error.
Được đề xuất
High-Temperature Sensor Amplification
The LT1007XH supports high-temperature sensor amplification because the manufacturer tests LT1007X devices at 200°C ±3°C and guarantees specified parameters at 190°C ±3°C. This capability is relevant to equipment operating near industrial ovens, furnaces, engines, or thermally exposed sensors where a conventional commercial amplifier may lose accuracy or fail. The amplifier’s 10 µV offset and 0.2 µV/°C drift remain important because temperature changes are intrinsic to the application. Designers must still distinguish guaranteed operating parameters from the 225°C absolute maximum operating temperature and should verify thermal stability in the completed assembly.
Được đề xuất
Low-Level Audio and Communication Interfaces
The LT1007XH can amplify low-level signals in audio and communication equipment when low voltage noise is more important than switching-converter efficiency or very wide bandwidth. Its 2.5 nV/√Hz noise density and 2 Hz 1/f corner reduce amplifier-added noise over the measured signal band, while 130 dB common-mode rejection helps reject common-mode interference. The TO-5 package is less compact than modern surface-mount packages, making the LT1007XH more relevant to established precision, aerospace-style, or high-reliability equipment than to compact consumer designs. Input and output loading must be checked against the complete gain and bandwidth design.
Được đề xuất
Laboratory Measurement Equipment
The LT1007XH is suitable for laboratory measurement equipment requiring a stable, low-noise amplifier rather than a general-purpose op amp. The combination of 10 µV offset voltage, 0.2 µV/°C drift, 130 dB common-mode rejection, and 60 nV peak-to-peak low-frequency noise supports accurate conditioning of small measurement signals. Its ability to operate in elevated-temperature conditions also supports specialized environmental and thermal test chambers. When replacing an earlier OP-27 design, engineers should verify the power-supply range, stability at the intended closed-loop gain, output swing, and the exact TO-5 lead configuration before production use.
Được đề xuất
Industrial Analog Signal Conditioning
The LT1007XH can serve in industrial analog signal-conditioning modules that process small sensor outputs in electrically noisy environments. Its 130 dB common-mode rejection and 130 dB power-supply rejection improve tolerance of unwanted common-mode and supply-related disturbances, while low noise and drift preserve measurement integrity. The hermetic TO-5 construction and 200°C test capability are useful in elevated-temperature equipment, although the complete enclosure, connector system, and thermal path determine practical reliability. Protection networks, input filtering, and grounding should be designed around the actual source impedance and operating bandwidth.

Ghi chú thiết kế
Use the LT1007X datasheet’s guaranteed limits at 190°C ±3°C when designing around elevated-temperature operation; the 225°C value is an absolute maximum and is not a recommended operating point. Because parameters change rapidly with temperature, calculate worst-case offset drift from the specified 0.2 µV/°C and include the complete thermal environment, lead-frame heat path, and adjacent heat sources. The 200°C ±3°C test condition is a production test condition, not permission to operate continuously at the test ceiling.
Do not replace LT1007XH with LT1007M without reviewing the separate operating-temperature specifications. The manufacturer explicitly directs users to the LT1007M datasheet for normal operating-temperature limits, while LT1007X devices receive elevated-temperature testing. Also verify the exact TO-5 lead configuration and the alternative’s offset, drift, noise, rejection, supply-voltage, and output-swing limits. Package match alone does not prove that every electrical limit is identical.
Place the amplifier’s input and output paths away from switching nodes, high-current returns, and long parallel traces that can capacitively couple interference into the low-noise input stage. Use short ground returns and a quiet analog ground strategy appropriate to the system. Include input-referenced compensation or source-resistance analysis because the 2.5 nV/√Hz voltage-noise figure does not include all noise introduced by the source impedance or bias current.
Do not treat the OP-27-family compatibility statement as permission to substitute any OP-27 orderable code. Verify temperature grade, supply range, offset limits, drift, gain bandwidth, slew rate, output swing, input common-mode range, and the physical pinout against both datasheets. The verified excerpts establish family-level replacement intent but do not provide every alternative’s numeric limits, so those limits must be confirmed in the applicable manufacturer documentation.
Thông tin tuân thủ
The supplied Analog Devices and distributor excerpts do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status for LT1007XH. AEC-Q100 is treated as not applicable because this is an Analog Devices precision operational amplifier, not an identified automotive-qualified product.
