Product details
Overview
LT6202IS8#PBF from Analog Devices (formerly Linear Technology) is a single-channel, rail-to-rail input and output operational amplifier optimized for low-noise, low-power signal conditioning in precision analog front-ends. It delivers 1.9nV/√Hz input voltage noise at 100kHz, 100MHz gain bandwidth, 25V/µs slew rate, and draws only 2.5mA per amplifier at 5V supply - enabling high-fidelity amplification in battery-powered data acquisition and sensor interface circuits.
For engineers reviewing the LT6202IS8#PBF datasheet, LT6202IS8#PBF pinout, LT6202IS8#PBF application, or LT6202IS8#PBF equivalent, key selection criteria include its guaranteed –40°C to 85°C operating range, 8-pin SO package with standard op amp pinout, rail-to-rail output swing within 35mV of rails at 5mA, and ultralow noise performance critical for driving high-resolution ADCs and active filters.
Technical Context
The LT6202IS8#PBF employs a proprietary bipolar complementary input stage enabling rail-to-rail common-mode input range (including both supply rails) and rail-to-rail output swing while maintaining unity-gain stability. Its 100MHz gain bandwidth and 25V/µs slew rate support wideband closed-loop configurations up to 10MHz without phase margin degradation.
It achieves 1.9nV/√Hz noise density at 100kHz and 800nVP-P integrated 0.1Hz–10Hz noise, with input bias current as low as ±1.3µA and CMRR of 90dB typical - making it suitable for high-impedance transducer interfaces where noise, offset drift, and common-mode rejection are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise Voltage Density | 1.9nV/√Hz at 100kHz - enables sub-16-bit SNR preservation in 100kHz-bandwidth sensor signal chains |
| Gain Bandwidth Product | 100MHz - supports stable closed-loop gains ≥10 at 10MHz signal frequencies |
| Slew Rate | 25V/µs - ensures <100ns 0.1% settling for 2V step inputs in fast-settling buffer applications |
| Supply Current | 2.5mA per amplifier at 5V - allows dual-channel operation under 6mA total for portable instrumentation |
| Input Common-Mode Range | Includes V– and V+ rails - eliminates level-shifting need for ground-referenced or single-supply sensors |
| Output Swing | Within 35mV of rails at 5mA load - maximizes dynamic range when driving 16-bit SAR ADCs with 5V reference |
| CMRR | 90dB typical - rejects >30mV of common-mode interference in noisy industrial environments |
Pinout & Package
LT6202IS8#PBF is housed in an 8-lead plastic SO (S8) package with standard op amp pinout and JEDEC MS-012AC footprint (5.0mm × 6.2mm, 1.27mm pitch). Thermal resistance θJA = 190°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output node - capable of sourcing/sinking ≥30mA, swings rail-to-rail under 5mA load |
| 2 | –IN | Inverting input - high-impedance node (12kΩ differential, 4MΩ common-mode) with ±1.3µA max bias current |
| 3 | +IN | Non-inverting input - identical impedance and bias characteristics as –IN; supports full rail-to-rail common-mode range |
| 4 | V– | Negative supply terminal - connects to ground or negative rail; underside metal pad (in DFN variants) tied to V–, not present in SO |
| 5 | NC | No connect - internally unconnected; must remain floating or grounded per layout guidelines |
| 6 | NC | No connect - internally unconnected; must remain floating or grounded per layout guidelines |
| 7 | NC | No connect - internally unconnected; must remain floating or grounded per layout guidelines |
| 8 | V+ | Positive supply terminal - operates from 2.5V to 12.6V total supply; PSRR = 74dB typical |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4897-1ARJZ-R7 | Lower 1.1nV/√Hz noise but higher 3.6mA supply current; 200MHz GBW; requires external compensation for unity-gain stability | Better suited for ultra-low-noise, high-speed (>50MHz) applications where power is secondary | Select if noise budget is <1.5nV/√Hz and bandwidth >100MHz is required; avoid for simple unity-gain buffers without compensation design |
| OPA333AIDBVR | Zero-drift architecture (0.02µV/°C drift), lower 17µV max VOS, but 6.5MHz GBW and 1.2nV/√Hz noise at 10kHz only | Ideal for DC-precision, low-frequency (<100kHz) sensor interfaces where offset drift dominates error budget | Select for microvolt-level DC accuracy in weigh scales or thermopile amplifiers; avoid for >1MHz signal bandwidth needs |
Compared with ADA4897-1ARJZ-R7 and OPA333AIDBVR, the LT6202IS8#PBF uniquely balances 100MHz bandwidth, 1.9nV/√Hz noise, unity-gain stability, and 2.5mA power in a standard SO-8 package - making it optimal for wideband, battery-constrained, precision analog front-ends requiring no external compensation.

FAQ
What is the operating temperature range guaranteed for LT6202IS8#PBF?
The LT6202IS8#PBF is specified and tested over the industrial temperature range of –40°C to +85°C. This guarantee covers all electrical parameters in the datasheet, including input offset voltage, noise, gain bandwidth, and output swing - unlike the 'C' grade which is only characterized from 0°C to 70°C. The 'I' suffix explicitly denotes this extended qualification.
Does LT6202IS8#PBF require external compensation for unity-gain stability?
No, the LT6202IS8#PBF is internally compensated and unity-gain stable. It does not require external capacitors or feedback network adjustments to maintain phase margin in voltage-follower (gain = +1) or inverting gain-of-one (gain = –1) configurations - simplifying layout and reducing bill-of-materials cost compared to decompensated high-speed op amps.
What is the maximum supply voltage for LT6202IS8#PBF?
The absolute maximum total supply voltage (V+ to V–) for LT6202IS8#PBF is 12.6V, as specified in the Absolute Maximum Ratings table. Operation is fully characterized from 2.5V to 12.6V total supply, including single-supply (e.g., 3.3V, 5V) and split-supply (e.g., ±5V) configurations. Exceeding 12.6V risks permanent device damage.
Can LT6202IS8#PBF drive a 100Ω load rail-to-rail?
The LT6202IS8#PBF can source/sink ≥30mA, enabling rail-to-rail output swing into loads ≥167Ω at 5V supply (per VOL/VOH specs: ≤35mV from rails at 5mA). Into 100Ω, output swing compresses - e.g., at ISINK = 15mA, VOL = 210mV (typical) - so full rail-to-rail performance is not maintained at 100Ω. For such loads, consider buffer stages or higher-output-current amplifiers.
Is LT6202IS8#PBF pin-compatible with other op amps in SO-8 packages?
Yes, the LT6202IS8#PBF uses the industry-standard SO-8 op amp pinout (pin 1=OUT, pin 2=–IN, pin 3=+IN, pin 4=V–, pin 8=V+), matching devices like the OP27, AD822, and LM358. However, functional compatibility depends on bandwidth, noise, and supply current requirements - it is not a drop-in replacement for slower or higher-noise legacy op amps without verifying signal chain performance impact.
