Product details
Overview
LTC2058HMSE#PBF from Analog Devices is a dual, rail-to-rail output, zero-drift operational amplifier with 5μV max offset voltage, 0.025μV/°C max drift, and 2.5MHz gain-bandwidth product. It operates from ±2.375V to ±18V (4.75V–36V total supply), features shutdown mode, and delivers ultra-low 200nVP-P (DC–10Hz) input noise-ideal for precision thermocouple amplification and high-resolution data acquisition.
For engineers reviewing the LTC2058HMSE#PBF datasheet, LTC2058HMSE#PBF pinout, LTC2058HMSE#PBF application, or LTC2058HMSE#PBF equivalent, key selection criteria include guaranteed –40°C to +125°C operation, MSE-12 package with SD/SDCOM control pins, rail-to-rail swing into 1kΩ, and 150dB PSRR/CMRR enabling stable performance in noisy industrial sensor front-ends.
Technical Context
The LTC2058HMSE#PBF employs auto-zeroing and chopper stabilization to suppress 1/f noise and offset drift, achieving sub-microvolt DC precision over temperature and time. Its internal 100kHz chopping frequency is actively suppressed to minimize ripple-typical output ripple is <1µVRMS at 100kHz.
Unlike basic zero-drift op amps, it integrates dedicated shutdown control (SD/SDCOM pins) with defined thresholds (0.8V low, 2.0V high), enabling low-power sleep states while maintaining V– referenced exposed pad thermal management and guard ring isolation for high-impedance inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | 4.75V to 36V total (±2.375V to ±18V); supports single-supply 5V/12V/24V and dual-supply ±5V/±15V systems without rail translation. |
| Offset Voltage | 5μV maximum; enables direct interfacing with µV-level sensors (e.g., thermocouples, strain gauges) without external trimming. |
| Offset Drift | 0.025μV/°C maximum (–40°C to +125°C); ensures <0.3μV total drift over full industrial temperature range. |
| Input Noise | 200nVP-P (DC–10Hz), 9nV/√Hz @1kHz; preserves signal integrity in low-frequency, high-gain sensor conditioning stages. |
| Gain Bandwidth | 2.5MHz typical; supports closed-loop gains up to ~100 at 25kHz while maintaining phase margin >60° with 100pF load. |
| Slew Rate | 1.6V/μs rising, 1.7V/μs falling; sufficient for 10V step response settling within 10µs to 0.1% in unity-gain buffer configurations. |
| PSRR / CMRR | 150dB typical; rejects power supply ripple and common-mode interference in unshielded industrial environments. |
| Shutdown Current | 9µA maximum (–40°C to +125°C); reduces system standby power by >99% versus active mode (1.6mA per amp). |
Pinout & Package
The LTC2058HMSE#PBF is housed in a 12-lead plastic MSOP (MSE) package with exposed thermal pad connected to V–. Pin 13 (exposed pad) must be soldered to PCB ground plane for thermal and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SD (Pin 1) | Shutdown enable control input | Active-high logic: drives amplifier into ultra-low-current state when SD–SDCOM ≥2.0V; compatible with 1.8V/3.3V/5V GPIO. |
| V– (Pin 2) | Negative supply rail | Reference for all internal circuitry and exposed pad; must be low-impedance path to system ground or negative rail. |
| OUTA (Pin 3) | Amplifier A output | Rail-to-rail capable: swings within 15mV of V– and 18mV of V+ under 1mA load at +125°C. |
| GUARD (Pin 4) | Guard ring terminal | No internal connection; ties to PCB guard trace around +INA/–INA to reduce leakage and EMI coupling in high-Z sensor paths. |
| –INA (Pin 5) | Amplifier A inverting input | Zero-drift input with 1012Ω||20pF common-mode impedance; accepts signals down to V– – 0.1V. |
| +INA (Pin 6) | Amplifier A noninverting input | Matches –INA specs; differential input voltage rating ±6V allows safe overvoltage tolerance during fault conditions. |
| +INB (Pin 7) | Amplifier B noninverting input | Electrically identical to +INA; dual-channel layout enables matched gain/phase response in differential or instrumentation topologies. |
| –INB (Pin 8) | Amplifier B inverting input | Matches –INA specs; independent bias current paths prevent cross-channel interaction in multi-stage filters. |
| GUARD/NC (Pin 9) | Guard ring / no-connect | Unused guard terminal; leave floating or tie to same guard net as Pin 4 for symmetry in PCB layout. |
| OUTB (Pin 10) | Amplifier B output | Identical performance to OUTA; supports independent channel shutdown via shared SD/SDCOM control. |
| V+ (Pin 11) | Positive supply rail | Accepts up to 40V absolute max; PSRR rejection maintains accuracy even with noisy switching supply rails. |
| SDCOM (Pin 12) | Shutdown reference node | Internal reference for SD threshold detection; must be tied to V– or stable low-noise bias point (V– to V+–2V range). |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Auto-zero + chopper hybrid eliminates 1/f noise and guarantees <5μV offset and <0.025μV/°C drift across –40°C to +125°C. |
| Rail-to-rail output | Swings within 15mV of either rail at +125°C with 1mA load-enables full-scale utilization of ADC reference ranges in single-supply systems. |
| High PSRR/CMRR | 150dB typical rejection of supply ripple and common-mode interference ensures stable DC gain in motor drive or power supply monitoring applications. |
| Dedicated shutdown | Two-pin (SD/SDCOM) control with hysteresis-free thresholds enables deterministic low-power states without external logic or level-shifting components. |
| Guard ring terminals | Two isolated GUARD pins allow PCB guard traces around both input pairs-critical for pA-level bias current control in pH or photodiode circuits. |
| Exposed thermal pad | V–-connected pad reduces θJA to 40°C/W, enabling reliable operation at 125°C ambient in compact industrial enclosures without forced air. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8628ARZ | Single-channel, SOIC-8; 1μV max offset, 0.002μV/°C drift, but no shutdown and only 2MHz GBW. | Lacks dual-channel integration and shutdown-requires two devices and external power gating for equivalent functionality. | Select when single-channel operation suffices and lowest possible drift is prioritized over integration and power control. |
| LTC2057HMS8E#PBF | Single-channel, SO-8; identical offset/noise specs but no shutdown pins and 8-lead package limits routing density. | Missing SD/SDCOM control and guard rings-unsuitable for space-constrained, low-power, or ultra-high-Z sensor designs. | Select when board area is constrained and dual-channel functionality is unnecessary; verify thermal derating for 125°C operation. |

FAQ
What is the operating temperature range specified for the LTC2058HMSE#PBF?
The LTC2058HMSE#PBF is rated for continuous operation from –40°C to +125°C. This H-grade qualification is explicitly confirmed in the Absolute Maximum Ratings table and Electrical Characteristics sections of the official datasheet, with all key parameters-including offset voltage, drift, and supply current-guaranteed across this full range.
Does the LTC2058HMSE#PBF require external capacitors on the SD and SDCOM pins for stable shutdown operation?
No, the LTC2058HMSE#PBF does not require external capacitors on SD or SDCOM. The shutdown comparator is internally compensated, and the datasheet specifies valid operation with direct connection of SD and SDCOM to control logic or resistive dividers. Adding capacitance may slow transition times but is not necessary for functional reliability of the LTC2058HMSE#PBF.
How does the guard ring (GUARD pins) function in the LTC2058HMSE#PBF, and what is its recommended PCB implementation?
The GUARD pins (4 and 9) on the LTC2058HMSE#PBF connect to an internal guard ring surrounding the input transistors. They must be routed to a low-impedance, quiet copper trace surrounding the +INA/–INA and +INB/–INB nets-ideally tied to the same potential as the input common-mode voltage. This reduces leakage current and EMI pickup in high-impedance sensor interfaces, directly improving long-term stability of the LTC2058HMSE#PBF.
Can the LTC2058HMSE#PBF drive a 1000pF capacitive load while maintaining stability?
The LTC2058HMSE#PBF is unity-gain stable but exhibits increasing overshoot with capacitive loads >100pF. At 1000pF, small-signal overshoot exceeds 90% and settling time degrades significantly. For loads >100pF, Analog Devices recommends adding a series resistor (RS = 5Ω–50Ω) between the output and capacitor, as validated in Figure 2058 G50 of the datasheet, to preserve stability and transient response of the LTC2058HMSE#PBF.
What is the maximum allowable differential input voltage for the LTC2058HMSE#PBF, and how does it impact overvoltage protection?
The absolute maximum differential input voltage for the LTC2058HMSE#PBF is ±6V (+IN to –IN), as stated in the Absolute Maximum Ratings table. Exceeding this risks permanent damage to the input ESD structures. Unlike some op amps with integrated clamps, the LTC2058HMSE#PBF relies on external protection (e.g., series resistors + TVS diodes) when interfacing with signals that may exceed ±6V-this specification defines the hard limit for safe operation of the LTC2058HMSE#PBF.
