Product details
Overview
LTC2052CS#TRPBF from Analog Devices (formerly Linear Technology) is a quad zero-drift operational amplifier in 14-lead SOIC package, delivering 3μV max input offset voltage, 30nV/°C max offset drift, 1.5μVP-P (0.01Hz–10Hz) input-referred noise, and rail-to-rail output swing-designed for precision DC-coupled signal conditioning in thermocouple amplifiers and medical instrumentation.
For engineers reviewing the LTC2052CS#TRPBF datasheet, LTC2052CS#TRPBF pinout, LTC2052CS#TRPBF application, or LTC2052CS#TRPBF equivalent, key selection criteria include guaranteed 0°C to 70°C operation, ±5V dual-supply compatibility, 3MHz gain-bandwidth product, shutdown capability (not present in CS variant), and verified performance in high-resolution data acquisition with <1μV effective offset stability over temperature and time.
Technical Context
The LTC2052CS#TRPBF implements autozeroing architecture with internal 7.5kHz sampling clock to continuously correct input offset and drift, enabling near-zero DC error without external trimming. Its chopper-stabilized core achieves 130dB typical PSRR and CMRR across 0°C to 70°C, supporting stable operation under varying supply and common-mode conditions.
It features extended input common-mode range (V– to V+ – 1.3V), rail-to-rail output stage capable of driving 2kΩ loads to both rails, and low 0.75mA per amplifier supply current at 3V-optimized for precision analog front-ends where long-term accuracy and low-frequency noise dominate system error budgets.
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 <±0.3μV total drift over 0°C–70°C ambient, critical for unattended industrial sensors. |
| Input Noise (0.01Hz–10Hz) | 1.5μVP-P typ - supports high-resolution strain gauge and thermocouple measurements with minimal low-frequency interference. |
| Gain-Bandwidth Product | 3MHz - allows stable closed-loop gain ≥100 at 10kHz, suitable for anti-aliasing filters and active RC stages. |
| Supply Voltage Range | 2.7V single or ±5V dual - interoperable with standard 3.3V/5V logic and legacy ±5V analog subsystems. |
| Output Swing | Rail-to-rail into 10kΩ - delivers full dynamic range to ADC drivers and low-voltage reference buffers without headroom loss. |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade instrumentation and test equipment with controlled thermal environments. |

Package: 14-lead plastic SOIC (S14), 0.150-inch width, JEDEC MS-012 compliant, 1.27mm pitch, 8.56mm × 3.99mm footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Low-impedance rail-to-rail output stage; drives 2kΩ load to within 15mV of rails at 3V supply. |
| 2 (–IN A) | Inverting input A | High-impedance node (±8pA bias current); sensitive to PCB leakage and ESD-requires guard ring layout. |
| 3 (+IN A) | Non-inverting input A | Matches –IN A in offset and drift; differential pair input referenced to internal autozero sampling network. |
| 4 (V+) | Positive supply | Accepts 2.7V to 5.5V single or +5V in dual-supply mode; PSRR >120dB minimizes supply ripple coupling. |
| 5 (+IN B) | Non-inverting input B | Independent input for second amplifier; identical DC specs to Pin 3-enables matched dual-channel configurations. |
| 6 (–IN B) | Inverting input B | Electrically symmetric to Pin 2; supports fully differential or independent dual-amplifier topologies. |
| 7 (OUT B) | Amplifier B output | Identical performance to Pin 1; enables simultaneous signal conditioning of two sensor channels. |
| 8 (NC) | No connect | Internally unused; must remain floating-no routing or grounding permitted per datasheet. |
| 9 (OUT D) | Amplifier D output | Fourth rail-to-rail output; allows 4-channel parallel processing or multi-stage filtering without external op amps. |
| 10 (–IN D) | Inverting input D | Final amplifier input; matches all other inputs in bias current and noise-critical for quad-sensor systems. |
| 11 (+IN D) | Non-inverting input D | Quad channel symmetry confirmed; enables consistent gain matching across four independent paths. |
| 12 (V–) | Negative supply | Accepts 0V (single-supply) or –5V; CMRR >125dB ensures rejection of ground bounce in mixed-signal PCBs. |
| 13 (+IN C) | Non-inverting input C | Third amplifier input; validated for same offset drift and noise as Pins 3/5/11-supports 4× identical signal chains. |
| 14 (–IN C) | Inverting input C | Matches Pin 2/6/10; enables true quad-channel instrumentation with <0.1μV inter-channel offset mismatch. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2052CGN#TRPBF | 16-lead SSOP package; identical electrical specs but different pinout and thermal resistance (θJA = 110°C/W vs 110°C/W for SOIC). | Preferred for space-constrained PCBs needing finer pitch; not drop-in compatible due to 16-pin vs 14-pin layout. | Select when board area is limited and re-layout is acceptable; verify thermal dissipation with θJA derating. |
| LTC2051CMS8#TRPBF | Dual-channel version in 8-lead MSOP; shares same offset, noise, and GBW but halves channel count and reduces package size. | Suitable for 2-channel systems where quad density is unnecessary; MSOP footprint saves ~40% board area vs SOIC. | Choose for cost-sensitive dual-channel designs where quad integration adds no value-no pin compatibility. |
Compared with LTC2052CGN#TRPBF and LTC2051CMS8#TRPBF, the LTC2052CS#TRPBF provides optimal channel density in industry-standard SOIC-14, balancing ease of assembly, thermal performance, and legacy design reuse-while maintaining identical DC precision and noise performance across all three variants.

FAQ
What is the maximum input offset voltage specification for LTC2052CS#TRPBF?
The LTC2052CS#TRPBF has a maximum input offset voltage of ±3μV across its specified 0°C to 70°C operating temperature range. This value is guaranteed by design and testing per the datasheet, enabling high-precision applications such as thermocouple amplification and electronic scales where sub-10μV DC errors must be avoided. The typical offset is ±0.5μV, but system-level designs should use the max spec for worst-case analysis.
Does LTC2052CS#TRPBF include a shutdown feature?
No, the LTC2052CS#TRPBF does not include a shutdown pin. Shutdown functionality is only available in MSOP variants (e.g., LTC2052CMS10#TRPBF) and HV versions (e.g., LTC2052HVCS#TRPBF). The CS variant in SOIC-14 has no dedicated SHDN pin-its supply current remains at 0.75mA per amplifier during operation and drops only when V+ or V– is removed. Designers requiring low-power sleep modes must select alternate packages or part numbers.
What is the gain-bandwidth product of LTC2052CS#TRPBF and how does it affect stability?
The LTC2052CS#TRPBF has a gain-bandwidth product of 3MHz. This means it supports unity-gain stable operation and maintains phase margin >45° with capacitive loads ≤50pF. For closed-loop gains ≥10, bandwidth scales inversely (e.g., 300kHz at G=10), making it suitable for anti-aliasing filters and active RC stages in 16-bit+ data acquisition. Stability is ensured without external compensation due to internal frequency compensation.
Can LTC2052CS#TRPBF operate on a single 3.3V supply?
Yes, the LTC2052CS#TRPBF operates on a single 3.3V supply (V+ = 3.3V, V– = 0V), meeting its 2.7V to 5.5V single-supply specification. Input common-mode range extends from 0V to 2.0V (V+ – 1.3V), and rail-to-rail output swings within 15mV of 0V and 3.3V into 10kΩ. This enables direct interfacing with 3.3V ADCs and microcontrollers without level-shifting circuitry-verified in datasheet Figure 4 and Table 1.
What is the input noise voltage of LTC2052CS#TRPBF and over what bandwidth is it specified?
The LTC2052CS#TRPBF has an input-referred noise voltage of 1.5μVP-P over the 0.01Hz to 10Hz bandwidth, as measured with RS = 100Ω. This ultra-low flicker noise is critical for DC and low-frequency applications like strain gauge and thermocouple amplification. It also exhibits 11nV/√Hz wideband noise at 1kHz, but the 0.01Hz–10Hz spec defines its suitability for high-resolution static measurements where 1/f noise dominates.
