Product details
Overview
LT1807CS8#PBF from Analog Devices (formerly Linear Technology) is a dual rail-to-rail input and output precision operational amplifier optimized for high-frequency, low-distortion signal conditioning in 3V/5V systems. It delivers 325MHz gain-bandwidth, 140V/μs slew rate, –80dBc harmonic distortion at 5MHz, 3.5nV/√Hz input voltage noise, and 85mA output current - enabling high-fidelity driving of ADCs and video line applications.
For engineers reviewing the LT1807CS8#PBF datasheet, LT1807CS8#PBF pinout, LT1807CS8#PBF application, or LT1807CS8#PBF equivalent, key selection considerations include rail-to-rail swing within 20mV of supply rails, unity-gain stability, ±5V/3V/5V single-supply operation, shutdown pin compatibility, and SO-8 package thermal performance (θJA = 100°C/W).
Technical Context
The LT1807CS8#PBF integrates two independent high-speed amplifiers sharing a common 8-pin SO package with standard dual op amp pinout. Its fully complementary input stage enables rail-to-rail common-mode range (V– to V+) and output swing (within 20mV of rails), while maintaining 106dB CMRR and 105dB PSRR at DC.
It employs a current-feedback-like architecture to achieve 325MHz GBW and 140V/μs slew rate without external compensation, remaining unity-gain stable into 100Ω loads. The SHDN pin (Pin 5) controls both amplifiers simultaneously with 80ns turn-on and 50ns turn-off times.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 325MHz - supports closed-loop bandwidth >100MHz at moderate gains for high-speed filtering and buffering. |
| Slew Rate | 140V/μs - enables clean 5MHz sine wave reproduction with <0.01% distortion and fast settling (120ns to 0.01%). |
| Input Voltage Noise | 3.5nV/√Hz at 10kHz - preserves SNR in precision sensor front-ends and low-level analog signal chains. |
| Output Current | ±85mA - drives 150Ω video loads or 1kΩ ADC inputs without gain compression or clipping. |
| Supply Range | 2.5V to 12.6V - operates from single 3V or 5V rails, or split ±5V supplies, with full rail-to-rail functionality. |
| Harmonic Distortion | –80dBc at 5MHz - meets NTSC video specs (ΔG = 0.01%, Δθ = 0.01°) and high-resolution data acquisition requirements. |
| Shutdown Current | 0.4mA per amplifier - reduces system power by >95% during idle periods while retaining fast wake-up capability. |
Pinout & Package
LT1807CS8#PBF uses an 8-lead plastic SO (Small Outline) package with θJA = 100°C/W, JEDEC MS-012AC compliant footprint, and Pb-free (RoHS-compliant) finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Amplifier A output | Delivers rail-to-rail output swing (20mV from rails) with 85mA drive capability; requires no series resistor for 100Ω loads. |
| 2: –IN A | Inverting input A | High-impedance node (2pF CIN) with rail-to-rail common-mode range; accepts signals from V– to V+. |
| 3: +IN A | Non-inverting input A | Matches –IN A in offset, bias, and noise; enables precision differential sensing and instrumentation configurations. |
| 4: V– | Negative supply / ground | Power return path; thermal performance depends on PCB copper area connected to this pin (θJA specified with 2oz trace). |
| 5: SHDN | Shutdown control input | Active-low logic input (VL ≤ 0.3V, VH ≥ V+ – 0.5V); sinks up to 400μA and disables both amps simultaneously. |
| 6: OUT B | Amplifier B output | Independent output identical to OUT A; allows dual-channel signal processing without cross-talk degradation. |
| 7: –IN B | Inverting input B | Matched to –IN A (≤300μV offset difference) for accurate dual-amplifier applications like differential drivers. |
| 8: +IN B | Non-inverting input B | Complements –IN B; channel-to-channel matching enables high-accuracy active filter and gain-stage pairing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables maximum dynamic range in low-voltage (3V) systems: full-scale signal utilization without headroom loss. |
| Unity-gain stable | Operates reliably at AV = 1 without external compensation, simplifying design of buffers and followers. |
| Low distortion at high frequency | –80dBc HD at 5MHz ensures fidelity in video line drivers and wideband data acquisition front-ends. |

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 |
|---|---|---|---|
| AD8066ARZ | Higher 145MHz GBW but lower 120V/μs slew rate; no shutdown pin; 1.8nV/√Hz noise. | Better noise performance in low-frequency sensor apps; lacks power-down for portable designs. | Select AD8066ARZ when ultra-low noise dominates over shutdown capability and high slew rate. |
| OPA2835IDR | Lower 31MHz GBW but 240V/μs slew rate; rail-to-rail I/O; 65mA output; no shutdown. | Superior slew for pulse applications; insufficient bandwidth for >10MHz signal chains. | Choose OPA2835IDR only for sub-30MHz, high-slew applications where shutdown is unnecessary. |
Compared with AD8066ARZ and OPA2835IDR, the LT1807CS8#PBF uniquely balances 325MHz bandwidth, 140V/μs slew, integrated shutdown, and rail-to-rail operation - making it optimal for power-aware, wideband dual-channel systems requiring minimal external components.

FAQ
What is the operating temperature range for the LT1807CS8#PBF?
The LT1807CS8#PBF is specified for 0°C to 70°C ambient operation. It is not rated for extended industrial (–40°C to 85°C) use - that requirement is met by the LT1807IS8#PBF variant. Thermal derating applies above 70°C due to θJA = 100°C/W and 150°C TJMAX.
Does the LT1807CS8#PBF support single-supply operation?
Yes, the LT1807CS8#PBF supports true single-supply operation from 2.5V to 12.6V. Its rail-to-rail input accepts signals from V– (ground) to V+, and its output swings within 20mV of both rails - enabling full-scale signal handling in 3V and 5V systems without level-shifting circuitry.
How does the shutdown pin (Pin 5) function on the LT1807CS8#PBF?
The SHDN pin on the LT1807CS8#PBF is an active-low control that disables both amplifiers simultaneously. Pulling Pin 5 ≤0.3V reduces supply current to 0.4mA total (0.2mA per amp), while asserting ≥(V+ – 0.5V) restores full operation with 80ns turn-on time. Leakage remains <1μA in shutdown.
Is the LT1807CS8#PBF unity-gain stable?
Yes, the LT1807CS8#PBF is explicitly unity-gain stable per its datasheet. It drives 100Ω loads at AV = 1 without oscillation or peaking, verified across 2.5V to 12.6V supplies and –40°C to 85°C (with appropriate derating). No external compensation is required for stable follower or buffer configurations.
What is the maximum capacitive load the LT1807CS8#PBF can drive without instability?
The LT1807CS8#PBF can directly drive up to 100pF with minimal overshoot (<5%) when a 10Ω series resistor is placed in series with the output. For larger loads (e.g., 1000pF), a 20–50Ω isolation resistor is required to maintain phase margin >45° and prevent ringing - confirmed in Figure G31/G32 of the LT1806/LT1807 datasheet.
