Product details
Overview
LTC2052HVCS#PBF from Analog Devices (formerly Linear Technology) is a quad zero-drift operational amplifier in a 14-lead SOIC package, designed for precision DC-coupled signal conditioning. It delivers maximum input offset voltage of 3μV, max offset drift of 30nV/°C, 1.5μVP-P (0.01Hz–10Hz) input-referred noise, rail-to-rail output swing, and operates from ±5V supplies with total supply voltage up to 12V - ideal for thermocouple amplification and high-resolution data acquisition systems.
For engineers reviewing the LTC2052HVCS#PBF datasheet, LTC2052HVCS#PBF pinout, LTC2052HVCS#PBF application, or LTC2052HVCS#PBF equivalent, key selection criteria include guaranteed 12V total supply rating, HV-grade common-mode input range extending to V+ – 1.3V, shutdown capability (in MSOP variants), and verified performance across –40°C to 125°C for industrial sensor front-ends.
Technical Context
The LTC2052HVCS#PBF uses 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 - enabling stable closed-loop operation in low-frequency precision filters and current-sense amplifiers.
It features enhanced input stage ESD protection, extended common-mode input range (V– to V+ – 1.3V), and rail-to-rail output capable of driving 2kΩ loads to both rails. Input bias current remains below ±150pA at 25°C and is dominated by charge injection effects below 70°C, not leakage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max ±3μV - enables sub-10μV system-level DC error in 16-bit+ data acquisition without calibration. |
| Offset Drift | Max ±30nV/°C - ensures <1μV total drift over 50°C ambient change, critical for unattended instrumentation. |
| Input Noise (0.01Hz–10Hz) | 1.5μVP-P - supports resolution better than 20-bit ENOB in DC-coupled sensor interfaces. |
| Supply Voltage Range | ±5V (12V total) - supports bipolar sensor excitation and true dual-supply signal chain integrity. |
| Gain-Bandwidth Product | 3MHz - sufficient for anti-alias filtering at ≤100kHz while preserving DC accuracy. |
| Common-Mode Rejection | Min 125dB - rejects >300V of common-mode interference on millivolt-level bridge outputs. |
| Output Swing | Rail-to-rail into 10kΩ - delivers full dynamic range to ADC drivers without level-shifting circuitry. |
Pinout & Package
Package: 14-lead plastic SOIC (S14), 0.150-inch width, JEDEC standard outline. Body dimensions: 8.56mm × 3.99mm × 1.75mm. Exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Low-impedance buffered output; drives 2kΩ load rail-to-rail with <15mV headroom. |
| 2 (–IN A) | Inverting input A | Differential input node; input bias current ≤±150pA at 25°C; sensitive to PCB leakage. |
| 3 (+IN A) | Non-inverting input A | Differential input node; matched to Pin 2 for CMRR optimization; requires symmetric layout. |
| 4 (V+) | Positive supply rail | Accepts up to +5.5V; must be bypassed with ≥0.1μF ceramic close to pin. |
| 5 (+IN B) | Non-inverting input B | Independent input for second amplifier; electrically isolated from A-channel inputs. |
| 6 (–IN B) | Inverting input B | Independent input for second amplifier; shares no internal nodes with Channel A. |
| 7 (OUT B) | Amplifier B output | Identical performance to Pin 1; channels are fully independent with no crosstalk specification. |
| 8 (NC) | No connect | Internally unused; must remain floating - no tie to ground or supply. |
| 9 (OUT D) | Amplifier D output | Fourth channel output; same specs as Pins 1 and 7; supports multi-channel synchronous sampling. |
| 10 (–IN D) | Inverting input D | Input for fourth amplifier; layout symmetry critical when used with Pin 11 (+IN D). |
| 11 (+IN D) | Non-inverting input D | Matches Pin 10; enables differential sensing on Channel D without external resistors. |
| 12 (V–) | Negative supply rail | Accepts down to –5.5V; return path for all four amplifiers; star-point grounding recommended. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2052HVCGN#PBF | 16-lead SSOP package; identical electrical specs; includes two NC pins (Pins 8 and 16); θJA = 110°C/W vs 110°C/W for SOIC. | Better thermal performance in high-density layouts; requires different footprint and stencil; no pinout compatibility with SOIC. | Select for space-constrained boards needing improved power dissipation or existing SSOP-based designs. |
| LTC2052HVIS#PBF | Same SOIC-14 package but rated for –40°C to 85°C; max offset voltage still ±3μV; HV supply rating (±5V) retained. | Not qualified for extended temperature operation; suitable for commercial/hospital-grade medical devices but not industrial or automotive under-hood. | Choose when full –40°C to 125°C operation is unnecessary and cost sensitivity favors lower-temperature grade. |
Compared with LTC2052HVCGN#PBF, LTC2052HVCS#PBF offers identical precision performance in a more widely adopted SOIC footprint, simplifying layout and rework; versus LTC2052HVIS#PBF, it adds guaranteed operation at 125°C - critical for engine control units and downhole sensors where ambient exceeds 85°C.

FAQ
What is the maximum total supply voltage rating for the LTC2052HVCS#PBF?
The LTC2052HVCS#PBF is rated for a maximum total supply voltage of 12V, supporting dual-supply configurations up to ±5V. This HV rating distinguishes it from standard LTC2052 variants (max 7V), enabling use with higher-voltage sensor excitation and improved noise immunity in industrial settings. The LTC2052HVCS#PBF maintains full DC specifications across this extended range.
Does the LTC2052HVCS#PBF include a shutdown function?
No, the LTC2052HVCS#PBF in the 14-lead SOIC (S14) package does not incorporate a shutdown pin. Shutdown functionality is only available in the 10-lead MSOP variants (e.g., LTC2052HVCMS10). The LTC2052HVCS#PBF operates continuously when powered and draws 0.75mA per amplifier at ±5V - a design choice prioritizing simplicity and DC stability over power gating.
What is the input common-mode voltage range for the LTC2052HVCS#PBF?
The LTC2052HVCS#PBF supports an extended input common-mode voltage range from V– to V+ – 1.3V. At ±5V supplies, this spans –5V to +3.7V - allowing direct interfacing with grounded sensors and single-ended sources without level-shifting. This range is maintained across the full –40°C to 125°C operating temperature, confirmed in the device's Electrical Characteristics table.
How does clock feedthrough affect system design when using the LTC2052HVCS#PBF?
The LTC2052HVCS#PBF uses a 7.5kHz autozeroing clock, resulting in two forms of clock feedthrough: input-referred residue (<1μVRMS) and source-impedance-dependent injection. To minimize impact, keep input source resistance <10kΩ and use feedback capacitors to limit closed-loop bandwidth. These measures reduce feedthrough to levels below the 1.5μVP-P broadband noise floor of the LTC2052HVCS#PBF.
Is the LTC2052HVCS#PBF pin-compatible with other LTC2052 variants in SOIC packages?
Yes, the LTC2052HVCS#PBF is pin-compatible with all other LTC2052 variants offered in the 14-lead SOIC (S14) package, including LTC2052CS, LTC2052IS, and LTC2052HVIS. All share identical pinout, footprint, and solder pad layout per JEDEC MS-012. However, electrical specifications differ - only the HV variants guarantee operation at ±5V supplies and extended temperature range.
