Product details
Overview
LTC2052IS#PBF from Analog Devices (formerly Linear Technology) is a quad zero-drift operational amplifier optimized for precision DC-coupled signal conditioning in high-resolution measurement systems. It delivers 3μV maximum input offset voltage, 30nV/°C max offset drift, 1.5μVP-P (0.01Hz–10Hz) input-referred noise, and rail-to-rail output swing - enabling accurate amplification of low-level sensor signals such as thermocouples and strain gauges in industrial instrumentation.
For engineers reviewing the LTC2052IS#PBF datasheet, LTC2052IS#PBF pinout, LTC2052IS#PBF application, or LTC2052IS#PBF equivalent, key selection criteria include guaranteed –40°C to +85°C operation, SO-14 package compatibility, dual-supply (±5V) and single-supply (3V/5V) support, and chopper-stabilized architecture eliminating DC drift without external calibration.
Technical Context
The LTC2052IS#PBF employs autozeroing with a 7.5kHz internal sampling clock to continuously correct input offset and drift. Its architecture includes separate chopper buffers per amplifier stage, achieving near-zero DC error while maintaining 3MHz gain-bandwidth product and 2V/μs slew rate.
It features extended common-mode input range (V– to V+ – 1.3V), 130dB typical CMRR and PSRR, and rail-to-rail output drive into 2kΩ loads - supporting high-accuracy closed-loop configurations in low-power, space-constrained applications where long-term stability is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max ±3μV - enables sub-10μV system-level DC error in precision sensor front-ends without trimming. |
| Offset Drift | Max ±30nV/°C - ensures <1μV total drift over full –40°C to +85°C operating range. |
| Input Noise (0.01Hz–10Hz) | 1.5μVP-P - supports 18-bit+ resolution in DC-coupled data acquisition with minimal flicker contribution. |
| Gain-Bandwidth Product | 3MHz - allows stable unity-gain and moderate-gain filtering (e.g., anti-aliasing) up to ~100kHz. |
| Supply Current per Amp | 1.0mA typ at 3V - enables four-channel precision amplification within 4mA total quiescent budget. |
| CMRR / PSRR | 130dB typ - rejects >1M:1 common-mode and supply ripple, critical for noisy industrial environments. |
| Output Swing | Rail-to-rail into 10kΩ; ±4.92V on ±5V - maximizes dynamic range and simplifies level-shifting in bipolar systems. |

FAQ
What is the maximum operating temperature range for the LTC2052IS#PBF?
The LTC2052IS#PBF is specified for operation from –40°C to +85°C. This industrial-grade temperature range is guaranteed across all electrical parameters including input offset voltage, drift, noise, and CMRR - making it suitable for deployment in factory automation, outdoor metering, and medical diagnostic equipment without thermal derating.
Does the LTC2052IS#PBF require external capacitors for stability?
No, the LTC2052IS#PBF is unity-gain stable and does not require external compensation capacitors. Its internal architecture is optimized for stable operation with capacitive loads up to 100pF. For heavier loads (>100pF), a small series resistor (10–50Ω) between output and load is recommended to maintain phase margin.
How does the autozeroing clock affect system-level noise performance in the LTC2052IS#PBF?
The LTC2052IS#PBF uses a 7.5kHz internal autozeroing clock. Residual clock feedthrough is <1μVRMS input-referred at 7.5kHz and is suppressed by proper layout: keep source impedances <10kΩ, use low-value feedback resistors, and add a capacitor across RF to limit closed-loop bandwidth below 7.5kHz if needed.
Can the LTC2052IS#PBF operate from a single 3V supply?
Yes, the LTC2052IS#PBF supports single-supply operation from 2.7V to 5.5V. At 3V, it delivers rail-to-rail output swing (within 60mV of rails into 10kΩ), 1.5μVP-P 0.01Hz–10Hz noise, and full functionality - ideal for portable, battery-powered instrumentation where low-voltage operation is mandatory.
Is the LTC2052IS#PBF pin-compatible with other members of the LTC2051/LTC2052 family?
No - the LTC2052IS#PBF (SO-14) is not pin-compatible with LTC2051 variants (e.g., MS8, DFN) or LTC2052 variants in SSOP (GN16) or narrow SO (S8) packages. Pin count, spacing, and terminal assignments differ across packages; PCB layout must be specific to the SO-14 footprint used by LTC2052IS#PBF.
