Product details
Overview
LT1807IMS8#PBF from Analog Devices (formerly Linear Technology) is a dual rail-to-rail input and output precision operational amplifier optimized for low-voltage, high-frequency signal conditioning. It delivers 325MHz gain-bandwidth, 140V/μs slew rate, 85mA output current, and –80dBc harmonic distortion at 5MHz, enabling high-fidelity driving of ADCs and active filters in ±5V or single 5V systems.
For engineers reviewing the LT1807IMS8#PBF datasheet, LT1807IMS8#PBF pinout, LT1807IMS8#PBF application, or LT1807IMS8#PBF equivalent, key selection considerations include its rail-to-rail I/O swing within 20mV of rails, 3.5nV/√Hz input voltage noise, –40°C to 85°C industrial temperature rating, MSOP-8 package, and dual-channel matching performance critical for differential signal paths.
Technical Context
The LT1807IMS8#PBF employs a complementary bipolar input stage enabling rail-to-rail common-mode input range and low distortion across supply voltages from 2.5V to 12.6V. Its unity-gain stable architecture supports high-speed closed-loop configurations without external compensation.
It features matched dual amplifiers with ≤200μV input offset voltage match and ≤0.03μA input bias current match (typ), ensuring precise differential gain accuracy. The shutdown pin (SHDN) enables fast 80ns turn-on and 50ns turn-off for power-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 325MHz - supports stable closed-loop operation up to 10MHz at AV = 2 with full-power bandwidth of 10MHz. |
| Slew Rate | 140V/μs - enables clean 2VP-P signal reproduction at 5MHz without slewing-induced distortion. |
| Input Voltage Noise | 3.5nV/√Hz - preserves SNR in front-end amplification stages before high-resolution ADCs. |
| Output Current | ±85mA - drives 150Ω video loads or 100Ω A/D converter inputs without external buffers. |
| Input Offset Voltage | 550μV max - ensures DC accuracy in precision instrumentation and sensor signal chains. |
| Supply Range | 2.5V to 12.6V - operates from single 3V/5V or split ±5V supplies, simplifying mixed-signal system power design. |
| Harmonic Distortion | –80dBc at 5MHz - meets SFDR requirements for 12-bit, 10Msps data acquisition systems. |
Pinout & Package
LT1807IMS8#PBF is housed in an 8-lead plastic MSOP package (3mm × 3mm, 0.65mm pitch) with exposed pad for thermal enhancement. Pin 1 is marked by a dot; the device is rated for –40°C to 85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Amplifier A output | Delivers rail-to-rail swing (within 20mV of V+ or V–) with 85mA drive capability. |
| 2: –IN A | Inverting input A | High-impedance node with 2pF input capacitance; accepts signals from V– to V+. |
| 3: +IN A | Non-inverting input A | Same rail-to-rail common-mode range as –IN A; matched offset/bias to –IN A. |
| 4: V– | Negative supply rail | Reference for both amplifiers; thermal pad connected internally to this pin. |
| 5: V+ | Positive supply rail | Supports single-supply (2.5V–12.6V) or dual-supply (±5V) operation. |
| 6: OUT B | Amplifier B output | Electrically identical to OUT A; channel-to-channel matching enables differential signaling. |
| 7: –IN B | Inverting input B | Matched to –IN A (≤200μV offset match) for precision differential gain stages. |
| 8: +IN B | Non-inverting input B | Matched to +IN A; enables true differential input configuration with common-mode rejection >100dB. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Input common-mode range spans V– to V+; output swings to within 20mV of either rail-maximizes dynamic range in low-voltage systems. |
| Low distortion at high frequency | –80dBc HD at 5MHz enables use in video line drivers and high-speed data acquisition without post-processing correction. |
| Dual-channel matching | ≤200μV input offset match and ≤0.03μA input bias match ensure accurate differential gain and common-mode rejection in instrumentation amps. |
| Shutdown control | Active-low SHDN pin reduces supply current to 0.4mA per amplifier, enabling power cycling in portable or battery-powered systems. |
| Wide supply flexibility | Operates from 2.5V single supply to ±5V dual supply-eliminates need for separate analog/digital rails in mixed-signal designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8622ARMZ | Lower GBW (56MHz), lower noise (1.3nV/√Hz), no shutdown pin, SO-8 only. | Better for ultra-low-noise DC-coupled sensor interfaces; unsuitable for >5MHz signal paths requiring fast settling. | Select when DC precision and low 1/f noise outweigh speed requirements; verify layout compatibility with SO-8 footprint. |
| OPA2350UA | Higher GBW (38MHz), higher slew rate (22V/μs), rail-to-rail I/O, SO-8 package, no shutdown. | Optimized for 3V–5.5V single-supply systems; lacks matching specs and high-frequency distortion data for precision differential use. | Prefer for cost-sensitive, moderate-speed portable applications where dual-channel matching is not required. |
Compared with AD8622ARMZ and OPA2350UA, the LT1807IMS8#PBF uniquely combines 325MHz bandwidth, –80dBc distortion at 5MHz, and guaranteed dual-channel matching in an MSOP-8 package-making it the only option among the three qualified for high-speed, precision differential signal conditioning across industrial temperature ranges.

FAQ
What is the maximum supply voltage for LT1807IMS8#PBF?
The LT1807IMS8#PBF has an absolute maximum total supply voltage (V+ to V–) of 12.6V. It is fully specified and characterized for operation from 2.5V to 12.6V, including ±5V (10V total) and single 5V or 3V supplies. Exceeding 12.6V risks permanent damage per Absolute Maximum Ratings.
Does LT1807IMS8#PBF support rail-to-rail input and output simultaneously?
Yes, the LT1807IMS8#PBF supports rail-to-rail input common-mode range (V– to V+) and rail-to-rail output swing (within 20mV of V+ or V– under load). This simultaneous capability is confirmed in the datasheet's "Description" and "Features" sections and enables full dynamic range utilization in low-voltage systems.
What is the typical input offset voltage match between channels for LT1807IMS8#PBF?
The LT1807IMS8#PBF specifies a typical input offset voltage match of 200μV between its two amplifiers at TA = 25°C (Note 10). Over the full –40°C to 85°C industrial temperature range, the maximum match is 1400μV, making it suitable for precision differential gain stages where channel tracking is critical.
Can LT1807IMS8#PBF drive a 150Ω video load with NTSC compliance?
Yes, the LT1807IMS8#PBF is explicitly characterized for NTSC video applications: it achieves 0.01% differential gain and 0.01° differential phase error when configured as a gain-of-2 amplifier driving a 150Ω load at ±5V supply-meeting broadcast-grade video signal integrity requirements.
Is the MSOP-8 package of LT1807IMS8#PBF thermally enhanced?
Yes, the MSOP-8 package used for LT1807IMS8#PBF includes an exposed thermal pad connected internally to the V– pin. With proper PCB copper land (2oz, ≥10mm²), θJA is reduced to 135°C/W, enabling reliable operation at full 85mA output current in industrial ambient temperatures up to 85°C.
