Product details
Overview
LTC2050HVCS8#TRPBF from Analog Devices is a zero-drift operational amplifier in an 8-lead SO package, designed for precision DC-coupled signal conditioning. It delivers 0.5µV typical input offset voltage, 10nV/°C offset drift, 1.5µVP-P (0.01Hz–10Hz) input-referred noise, and rail-to-rail output swing into 2kΩ loads-enabling high-accuracy thermocouple amplification and strain gauge measurement in industrial sensor front-ends.
For engineers reviewing the LTC2050HVCS8#TRPBF datasheet, LTC2050HVCS8#TRPBF pinout, LTC2050HVCS8#TRPBF application, or LTC2050HVCS8#TRPBF equivalent, key selection criteria include guaranteed 3µV max offset voltage, ±5.5V dual-supply operation, shutdown capability, AEC-Q100 qualification for automotive use, and compatibility with low-impedance sensor interfaces requiring sub-microvolt stability over temperature and time.
Technical Context
The LTC2050HVCS8#TRPBF employs auto-zeroing architecture with a 7.5kHz internal sampling clock to continuously correct input offset and 1/f noise, achieving near-zero DC error across –40°C to 125°C. Its input stage supports common-mode voltage from V– to (V+ – 1.3V), and its enhanced output stage drives rail-to-rail into 2kΩ while maintaining >130dB PSRR and CMRR.
It integrates an active-low shutdown pin (Pin 5) that reduces supply current to ≤3µA and places inputs/outputs in high-impedance state. The device operates from ±2.7V to ±5.5V total supply (12V max), with specified performance over 0°C to 70°C ambient per the 'C' grade suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±0.5µV typical; enables direct amplification of µV-level sensor signals without calibration drift. |
| Offset Drift | 10nV/°C typical; ensures <1µV total drift over 100°C temperature range-critical for unattended instrumentation. |
| Input Noise (0.01–10Hz) | 1.5µVP-P; supports high-resolution data acquisition down to 16-bit effective resolution at DC. |
| Supply Range | ±2.7V to ±5.5V; allows bipolar operation with standard ±5V rails and compatibility with legacy industrial systems. |
| Gain Bandwidth Product | 3MHz; sufficient for closed-loop gains up to 1000 at 3kHz signal bandwidth in precision filters and instrumentation amps. |
| Output Swing | Rail-to-rail into 2kΩ load; delivers full dynamic range from –4.75V to +4.75V on ±5V supplies-maximizing SNR in single-ended ADC interfaces. |
| Shutdown Current | ≤3µA; enables power-gating in battery-powered portable test equipment without sacrificing wake-up latency. |
Pinout & Package
Package: 8-lead plastic SO (narrow, 0.150-inch body width), JEDEC MS-012, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NC | No connect | Internal die pad; must remain floating or grounded per layout guidelines to avoid parasitic coupling. |
| 2 - V+ | Positive supply | Accepts +2.7V to +5.5V; requires local 0.1µF ceramic bypass capacitor placed within 2mm. |
| 3 - OUT | Amplifier output | Capable of sourcing/sinking ≥10mA; rail-to-rail swing into 2kΩ load ensures minimal headroom loss. |
| 4 - NC | No connect | Unused internal node; electrically isolated-no routing or grounding required. |
| 5 - SHDN | Active-low shutdown control | Pull ≤V– + 0.5V to enter shutdown; releases to high-impedance state with <1µs wake-up delay. |
| 6 - –IN | Inverting input | High-impedance node (input bias current ±1pA typ); sensitive to PCB leakage-guard ring recommended. |
| 7 - +IN | Non-inverting input | Matches –IN in offset and drift; differential pair symmetry enables >130dB CMRR up to 100Hz. |
| 8 - V– | Negative supply | Accepts –2.7V to –5.5V; symmetric with V+ for true bipolar operation and balanced PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zeroing at 7.5kHz eliminates 1/f noise and thermal drift-ensuring stable DC gain over decades of operation. |
| Rail-to-rail output stage | Drives loads from V– to V+ with <10mV saturation-preserves full-scale accuracy in 16-bit SAR ADC driver applications. |
| High PSRR/CMRR | ≥130dB at DC enables rejection of supply ripple and common-mode interference in noisy industrial environments. |
| Shutdown mode | Reduces quiescent current to ≤3µA while disabling internal clock-ideal for intermittent-sampling sensor nodes. |
| AEC-Q100 qualified | Validated for automotive underhood applications (Grade 3: –40°C to 125°C)-supports functional safety-critical sensing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2051CS8#TRPBF | Dual-channel version in same SO-8 package; identical offset (±0.5µV) and noise (1.5µVP-P), but no shutdown pin. | Preferred when two matched amplifiers are needed (e.g., I/V + filter stages) and space constraints prohibit dual SO-8s. | Select LTC2051CS8#TRPBF only if dual-channel functionality is required and shutdown is unnecessary. |
| LTC1150CN8#PBF | Higher voltage rating (±18V), larger offset (±5µV max), higher noise (3µVP-P), no shutdown, SO-8 package. | Suitable for high-voltage industrial controls where ±15V rails are standard and µV-level precision is secondary to robustness. | Choose LTC1150CN8#PBF only when operating beyond ±5.5V and sub-µV drift is not required. |
Compared with LTC2051CS8#TRPBF and LTC1150CN8#PBF, the LTC2050HVCS8#TRPBF uniquely combines ±5.5V operation, active shutdown, and 0.5µV typical offset in a single-channel SO-8-making it optimal for space-constrained, low-power, high-precision analog front-ends demanding long-term DC stability.

FAQ
What is the maximum supply voltage rating for the LTC2050HVCS8#TRPBF?
The LTC2050HVCS8#TRPBF has an absolute maximum total supply voltage (V+ to V–) of 12V. It operates over a recommended range of ±2.7V to ±5.5V, enabling true bipolar operation on standard ±5V rails. Exceeding 12V risks permanent damage per Absolute Maximum Ratings.
Does the LTC2050HVCS8#TRPBF support rail-to-rail input common-mode voltage?
No-the LTC2050HVCS8#TRPBF supports input common-mode voltage from V– up to (V+ – 1.3V), not full rail-to-rail. For example, on ±5V supplies, the usable input range is –5V to +3.7V. This limitation is inherent to its auto-zeroing input stage architecture and is documented in the Electrical Characteristics table.
How does the shutdown feature of the LTC2050HVCS8#TRPBF behave during power-up?
During power-up, the LTC2050HVCS8#TRPBF remains in normal operation until the SHDN pin (Pin 5) is actively pulled low. The shutdown pin has no power-on reset behavior-it defaults to active-high (normal operation) when left floating or tied to V+. No external pull-up is required for reliable startup.
Can the LTC2050HVCS8#TRPBF drive capacitive loads directly?
The LTC2050HVCS8#TRPBF is not unity-gain stable with heavy capacitive loads. Driving >100pF directly may cause peaking or oscillation. For capacitive loads >50pF, isolate with a series resistor (e.g., 10–100Ω) or use a dedicated buffer stage. Stability data is confirmed in Figure 8 (Gain/Phase vs Frequency) of the datasheet.
Is the LTC2050HVCS8#TRPBF pin-compatible with other SO-8 op amps like the LT1013 or OP27?
No-the LTC2050HVCS8#TRPBF uses a non-standard SO-8 pinout with NC pins (1 and 4) and SHDN on Pin 5, differing from industry-standard dual-op-amp layouts. Direct replacement would require PCB redesign. Always verify pin mapping against the S8 Package Drawing (Rev G) before integration.
