Product details
Overview
LTC2052HVHGN#PBF from Analog Devices (formerly Linear Technology) is a quad zero-drift operational amplifier in a 16-lead SSOP package, designed for ultra-precision DC-coupled signal conditioning. It delivers maximum input offset voltage of 3 μV, max offset drift of 30 nV/°C, 1.5 μVP-P (0.01 Hz to 10 Hz) input-referred noise, rail-to-rail output swing, and operates from ±5 V supplies with total supply voltage up to 12 V - enabling high-accuracy thermocouple amplification and strain gauge readout in industrial sensor interfaces.
For engineers reviewing the LTC2052HVHGN#PBF datasheet, LTC2052HVHGN#PBF pinout, LTC2052HVHGN#PBF application, or LTC2052HVHGN#PBF equivalent, key selection criteria include guaranteed –40°C to 125°C operation, HV-grade ±5 V supply support, 130 dB CMRR/PSRR, 3 MHz gain-bandwidth, and verified performance in low-side current sense and medical instrumentation front-ends where long-term DC stability is critical.
Technical Context
The LTC2052HVHGN#PBF employs autozeroing architecture with a 7.5 kHz internal sampling clock to continuously correct input offset and drift. Its chopper-stabilized core achieves near-zero DC error while maintaining low 1.5 μVP-P noise in the 0.01–10 Hz band - essential for sub-microvolt-level measurements in high-resolution data acquisition.
It features extended common-mode input range (V– to V+ – 1.3 V), rail-to-rail output drive into 2 kΩ loads, and robust 130 dB PSRR/CMRR across temperature and supply variations - making it suitable for precision analog front-ends where supply rejection and common-mode immunity directly impact measurement fidelity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max ±3 μV - ensures <1 μV residual error after autozero correction, critical for DC-accurate RC filters and electronic scales. |
| Offset Drift | Max ±30 nV/°C - enables stable µV-level accuracy over full –40°C to 125°C industrial temperature range. |
| Input Noise (0.01–10 Hz) | 1.5 μVP-P - supports 20+ bit effective resolution in slow-sampling applications like strain gauge bridges. |
| Supply Voltage Range | ±5 V (12 V total) - supports bipolar sensor excitation and true dual-supply operation without level-shifting. |
| Gain-Bandwidth Product | 3 MHz - provides sufficient bandwidth for anti-alias filtering and fast settling in precision ADC driver stages. |
| CMRR / PSRR | 130 dB (typ) - rejects power supply ripple and common-mode interference in noisy industrial environments. |
| Output Swing | Rail-to-rail into 10 kΩ - maximizes dynamic range when driving SAR or sigma-delta ADC inputs directly. |
Pinout & Package
Package: GN - 16-lead plastic SSOP (0.150″ narrow body, 3.81 mm × 9.91 mm footprint, 1.75 mm height). Exposed pad not present; standard SSOP thermal profile applies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Low-impedance buffered output capable of rail-to-rail swing into ≥2 kΩ load. |
| 2 (–IN A) | Inverting input A | Differential input node with pA-level bias current; sensitive to PCB leakage and ESD. |
| 3 (+IN A) | Non-inverting input A | High-impedance reference input; matched to Pin 2 for optimal CMRR. |
| 4 (V+) | Positive supply rail | Accepts +5 V (or +3 V); must be bypassed locally with ≥1 μF ceramic capacitor. |
| 5 (+IN B) | Non-inverting input B | Independent input for second amplifier; electrically isolated from A-channel inputs. |
| 6 (–IN B) | Inverting input B | Matched pair with Pin 5; maintains channel-to-channel tracking under common-mode shifts. |
| 7 (OUT B) | Amplifier B output | Identical performance to Pin 1; supports independent gain configurations per channel. |
| 8 (NC) | No connect | Internally unused; must remain unconnected and un-bonded on PCB. |
| 9 (OUT D) | Amplifier D output | Fourth output; shares same electrical specs as Pins 1 and 7 - enables 4-channel parallel or differential configurations. |
| 10 (–IN D) | Inverting input D | Final inverting input; layout symmetry with Pins 2 and 6 recommended for matching. |
| 11 (+IN D) | Non-inverting input D | Final non-inverting input; completes quad topology with consistent input impedance. |
| 12 (V–) | Negative supply rail | Accepts –5 V (or GND in single-supply mode); requires local bypassing identical to Pin 4. |
| 13 (+IN C) | Non-inverting input C | Third non-inverting input; enables simultaneous multi-sensor conditioning (e.g., 4-wire RTD + bridge). |
| 14 (–IN C) | Inverting input C | Third inverting input; supports fully independent fourth amplifier channel. |
| 15 (OUT C) | Amplifier C output | Third output; identical rail-to-rail capability and drive strength as other outputs. |
| 16 (NC) | No connect | Unused terminal; no internal connection; leave floating and un-routed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zero-drift operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2052HVCS#PBF | 14-lead SOIC package; same electrical specs but larger footprint and higher θJA (110°C/W vs 110°C/W - identical thermal rating but different board-level dissipation behavior). | Preferred for through-hole prototyping or legacy SOIC layouts; lacks SSOP's space efficiency for high-density PCBs. | Select when board real estate allows SOIC and hand-soldering or rework is required. |
| LTC2052IGN#PBF | Same GN package but –40°C to 85°C temp grade; identical pinout and AC/DC specs except reduced operating temperature ceiling. | Suitable for commercial-grade instrumentation where extended temperature qualification is unnecessary. | Choose for cost-sensitive designs with ambient temperature constraints below 85°C. |
Compared with LTC2052HVCS#PBF and LTC2052IGN#PBF, the LTC2052HVHGN#PBF uniquely combines 16-lead SSOP miniaturization, full –40°C to 125°C qualification, and HV-grade ±5 V supply support - making it the only option meeting all three requirements simultaneously for ruggedized, space-constrained precision analog systems.

FAQ
What is the maximum supply voltage for LTC2052HVHGN#PBF?
The LTC2052HVHGN#PBF supports a total supply voltage of up to 12 V, enabling operation from ±5 V rails. This HV variant exceeds the standard LTC2052's 7 V limit, allowing direct use with common industrial bipolar supplies without external regulation. Absolute maximum ratings specify V+ to V– ≤ 12 V; exceeding this risks permanent damage.
Does LTC2052HVHGN#PBF include shutdown functionality?
No, the LTC2052HVHGN#PBF does not feature a shutdown pin. Shutdown capability is present only in the 10-lead MSOP variants (e.g., LTC2051CMS10), not in the 16-lead GN package. The LTC2052HVHGN#PBF operates continuously when powered and draws ~1.5 mA per amplifier at ±5 V - design accordingly for power budgeting.
What is the input bias current specification for LTC2052HVHGN#PBF?
The LTC2052HVHGN#PBF has a typical input bias current of ±90 pA at 25°C and ±300 pA maximum over temperature. This low bias current minimizes voltage errors in high-impedance sensor interfaces such as piezoelectric transducers or pH electrodes, especially when combined with its 3 μV offset and 30 nV/°C drift.
Can LTC2052HVHGN#PBF drive capacitive loads directly?
The LTC2052HVHGN#PBF is not unity-gain stable with large capacitive loads. Driving >100 pF directly may cause peaking or oscillation. For ADC input buffering, use a series resistor (e.g., 10–50 Ω) between the LTC2052HVHGN#PBF output and the ADC input capacitance, or add a small isolation capacitor (≤100 pF) in the feedback path to maintain stability without degrading bandwidth.
Is LTC2052HVHGN#PBF RoHS compliant and lead-free?
Yes, the #PBF suffix indicates that the LTC2052HVHGN#PBF is lead-free and RoHS compliant. It uses matte tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements. Reflow profiles must follow Analog Devices' specified thermal ramp rates and peak temperature limits (≤260°C) to ensure solder joint integrity and avoid delamination.
