Product details
Overview
LTC2052HS#PBF from Analog Devices (formerly Linear Technology) is a quad zero-drift operational amplifier in an 8-lead SOIC package, designed for precision DC-coupled signal conditioning. It delivers maximum input offset voltage of 3μV, max offset drift of 30nV/°C, rail-to-rail output swing, and 1.5μVP-P (0.01Hz–10Hz) noise-enabling high-resolution thermocouple amplification and strain gauge measurement in industrial sensor interfaces.
For engineers reviewing the LTC2052HS#PBF datasheet, LTC2052HS#PBF pinout, LTC2052HS#PBF application, or LTC2052HS#PBF equivalent, key selection criteria include guaranteed –40°C to 125°C operation, ±5V supply compatibility, shutdown capability (in HV variants), and verified performance in low-side current sense and medical instrumentation circuits.
Technical Context
The LTC2052HS#PBF employs autozeroing architecture with a 7.5kHz internal sampling clock to continuously correct input offset and drift. Its chopper-stabilized core achieves near-zero DC error while maintaining 3MHz gain-bandwidth product and 2V/μs slew rate-supporting stable closed-loop operation in active RC filters and precision integrators.
It features extended common-mode input range (V– to V+ – 1.3V), rail-to-rail output stage capable of driving 2kΩ loads to both rails, and robust PSRR/CMRR (>120dB typical) across temperature and supply voltage variations-critical for high-common-mode-noise environments like motor control feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max ±3μV - enables sub-10μV system-level DC error in 24-bit DAQ front-ends without calibration. |
| Offset Drift | Max ±30nV/°C - ensures <±0.3μV total drift over full –40°C to 125°C range, eliminating thermal nulling circuitry. |
| Noise (0.01Hz–10Hz) | 1.5μVP-P - supports 20+ bit effective resolution in low-frequency sensor signal chains. |
| Gain-Bandwidth Product | 3MHz - allows stable unity-gain buffering and closed-loop gains up to ~100 at 30kHz. |
| Supply Current per Amp | 1.0mA typ (3V), 1.5mA typ (5V) - balances ultra-low drift with moderate power for always-on industrial sensors. |
| Operating Temp Range | –40°C to 125°C - qualified for under-hood automotive, industrial PLC I/O modules, and downhole equipment. |
| Output Swing (RL=2kΩ) | V+ – 0.15V / 15mV above V– - delivers true rail-to-rail dynamic range into moderate loads. |
Pinout & Package
Package: 8-lead plastic SOIC (S8), 0.150-inch width, JEDEC MS-012 compliant. Body dimensions: 4.90mm × 3.91mm × 1.75mm. Exposed pad not present.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or feedback network; rail-to-rail capable. |
| 2 | –IN A | Inverting input of Amp A - high-impedance node; sensitive to PCB leakage and ESD. |
| 3 | +IN A | Non-inverting input of Amp A - referenced to system ground or bias voltage in differential configurations. |
| 4 | V– | Negative supply rail - must be decoupled locally with 0.1μF ceramic capacitor. |
| 5 | +IN B | Non-inverting input of Amp B - electrically isolated from Amp A; used for independent channel routing. |
| 6 | –IN B | Inverting input of Amp B - shares no internal nodes with Amp A; enables dual-channel instrumentation. |
| 7 | OUT B | Amplifier B output - identical performance to OUT A; supports parallel or cascaded topologies. |
| 8 | V+ | Positive supply rail - accepts 2.7V to 5.5V single supply or ±2.5V to ±5V dual supply. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift autozeroing | Continuous correction of input offset and drift via 7.5kHz internal clock - eliminates manual nulling and thermal drift compensation. |
| Rail-to-rail output | Swings within 15mV of V– and 150mV of V+ into 2kΩ - maximizes dynamic range in single-supply systems. |
| High CMRR/PSRR | ≥120dB over –40°C to 125°C - rejects power supply ripple and common-mode interference in noisy industrial environments. |
| Low 1/f noise | 1.5μVP-P (0.01Hz–10Hz) - preserves signal integrity in DC-coupled bridge and thermocouple amplifiers. |
| Extended temp grade | Specified and tested from –40°C to 125°C - suitable for engine control units, solar inverters, and factory automation hardware. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2052HGN#PBF | 16-lead SSOP package; same electrical specs but different pinout and layout footprint. | Requires PCB redesign due to 16-pin GN vs 8-pin S8; better thermal resistance (θJA = 110°C/W). | Select when higher channel count density or improved thermal performance is needed in space-constrained designs. |
| AD8629ARZ | Single zero-drift op amp (not quad); 1μV max offset, 0.02μV/°C drift, 2.2MHz GBW, SOIC-8. | Requires four separate ICs for quad functionality; lacks guaranteed 125°C operation (rated –40°C to 125°C but not fully characterized). | Choose only if single-channel replacement suffices and lower drift specification justifies added board area and cost. |
Compared with LTC2052HGN#PBF, LTC2052HS#PBF offers identical performance in a smaller, lower-cost SOIC-8 footprint but with higher thermal resistance; versus AD8629ARZ, it provides integrated quad functionality with full 125°C qualification-reducing component count and validation effort in multi-channel systems.

FAQ
What is the maximum operating temperature specification for the LTC2052HS#PBF?
The LTC2052HS#PBF is fully specified and tested over –40°C to 125°C ambient temperature. This extended temperature grade is confirmed in the "Available Options" table and electrical characteristics sections of the datasheet, making it suitable for under-hood automotive, industrial motor control, and downhole sensing applications where ambient temperatures exceed 85°C.
Does the LTC2052HS#PBF include a shutdown pin?
No, the LTC2052HS#PBF does not include a shutdown pin. Shutdown functionality is only available on HV variants (e.g., LTC2052HVHS#PBF) and in MSOP packages (MS10), not in the SOIC-8 (S8) package of the LTC2052HS#PBF. The standard LTC2052HS#PBF operates continuously when powered within its supply voltage range.
What is the typical input bias current of the LTC2052HS#PBF at 25°C and 3V supply?
At TA = 25°C and VS = 3V, the typical input bias current of the LTC2052HS#PBF is ±8pA, with a maximum of ±50pA. This ultra-low bias current is critical for high-impedance sensor interfaces such as piezoelectric transducers and pH electrodes, minimizing voltage errors across source impedances exceeding 100MΩ.
Can the LTC2052HS#PBF operate from a single 3.3V supply?
Yes, the LTC2052HS#PBF operates from a single 2.7V to 5.5V supply, including standard 3.3V rails. Its rail-to-rail output stage delivers full swing from 15mV above V– to within 150mV of V+, and its input common-mode range extends from V– to V+ – 1.3V-enabling direct interfacing with 3.3V ADCs and microcontrollers without level-shifting.
How does the LTC2052HS#PBF achieve its low 1/f noise performance?
The LTC2052HS#PBF achieves 1.5μVP-P (0.01Hz–10Hz) noise through continuous autozeroing: an internal 7.5kHz clock samples and nulls input offset voltage in real time, effectively suppressing low-frequency drift and flicker noise. This architecture eliminates traditional 1/f noise corner issues seen in standard CMOS op amps, delivering flat noise density down to DC.
