Product details
Overview
LTC6259IMS#TRPBF from Analog Devices is a dual, rail-to-rail input/output, micropower operational amplifier in a 10-lead MSOP package. It delivers 1.3MHz gain-bandwidth, 20µA supply current per amplifier, 400µV max input offset voltage, and stable operation with capacitive loads up to 100nF - enabling precision signal conditioning in battery-powered instrumentation and automotive sensor interfaces.
For engineers reviewing the LTC6259IMS#TRPBF datasheet, LTC6259IMS#TRPBF pinout, LTC6259IMS#TRPBF application, or LTC6259IMS#TRPBF equivalent, key selection criteria include shutdown capability (7µA max), EMI rejection ratio (45dB at 1GHz), rail-to-rail I/O swing down to 30mV from rails, and guaranteed operation from –40°C to 125°C in the H-grade variant.
Technical Context
The LTC6259IMS#TRPBF employs a dual-input-stage architecture: a PNP pair active near V– and an NPN pair active near V+, enabling true rail-to-rail input common-mode range (–0.1V to V+ + 0.1V) and low input bias current (75nA max). Its C-Load™ compensation ensures unity-gain stability with ≥100nF capacitive loads without external compensation.
Shutdown control is implemented via an active-low SHDN pin referenced to V–, with defined thresholds (VIL = 0.6V, VIH = 1.5V) and fast turn-off (7µs) and turn-on (152µs at 5V). The output stage uses a common-emitter buffer capable of sourcing/sinking ≥4mA while maintaining rail-to-rail swing under load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.3MHz - enables stable closed-loop operation up to ~100kHz at gain ≥10 with minimal phase margin degradation. |
| Supply Current per Amp | 20µA - supports multi-year battery life in always-on sensor nodes operating from coin cells or energy harvesters. |
| Input Offset Voltage | ±400µV max - ensures ≤0.4% error in 1V full-scale DC-coupled measurement paths without trimming. |
| EMI Rejection Ratio | 45dB at 1GHz - suppresses RF-induced offset shifts in automotive or industrial EMI-heavy environments. |
| Capacitive Load Drive | 100nF - eliminates need for isolation resistors when driving ADC input filters or long PCB traces. |
| Rail-to-Rail Output Swing | 30mV from rails (1mA load) - preserves dynamic range in low-voltage (1.8V) systems where headroom is critical. |
| Shutdown Current | 7µA max - reduces system standby power by >99% vs active mode, enabling duty-cycled sensing. |
Pinout & Package
10-Lead Plastic MSOP (MS) package, 3mm × 3mm × 1.1mm, exposed pad connected to V–. Pin 1 marked with dot; pin numbering counterclockwise from dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - rail-to-rail capable, high-Z in shutdown, drives 4mA min into resistive loads. |
| 2 | –INA | Inverting input of Amp A - accepts common-mode voltage from V– – 0.1V to V+ + 0.1V. |
| 3 | +INA | Noninverting input of Amp A - identical voltage range and bias current spec as –INA. |
| 4 | V+ | Positive supply - operates from 1.8V to 5.25V; requires 0.1µF bypass capacitor to V–. |
| 5 | +INB | Noninverting input of Amp B - electrically isolated from Amp A; shares same V+ and V– rails. |
| 6 | –INB | Inverting input of Amp B - matched performance to Amp A inputs across temperature. |
| 7 | OUTB | Amplifier B output - independent of OUTA; same drive strength and swing specs. |
| 8 | NC | No connect - internal die pad; must remain unconnected on PCB. |
| 9 | SHDN | Active-low shutdown control - pulls supply current to ≤7µA when ≤0.6V relative to V–. |
| 10 | V– | Negative supply - typically ground; exposed pad must be soldered to PCB thermal plane. |
Key Features
| Feature | Design Value |
|---|---|
| C-Load™ Capacitive Load Drive | Stable unity-gain operation with 100nF load - removes need for output series resistor + shunt capacitor compensation. |
| Rail-to-Rail Input Range | –0.1V to V+ + 0.1V - enables direct interface to sensors with outputs extending beyond supply rails (e.g., thermocouples). |
| Low 1/f Noise | 2µVP-P (0.1Hz–10Hz) - minimizes drift errors in precision DC-coupled amplification of slow-varying signals. |
| High PSRR/CMRR | 90dB PSRR / 95dB CMRR - maintains accuracy in noisy supply or high-common-mode industrial sensor front-ends. |
| EMI Hardened Inputs | 45dB rejection at 1GHz - prevents RF rectification artifacts in automotive infotainment or ADAS subsystems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX44260ASA+T | Lower GBW (700kHz), higher supply current (35µA), no shutdown pin. | Suitable for non-shutdown, lower-bandwidth sensor buffers only. | Select when absolute lowest cost is prioritized over shutdown and bandwidth. |

FAQ
What is the maximum capacitive load the LTC6259IMS#TRPBF can drive stably in unity-gain configuration?
The LTC6259IMS#TRPBF is specified to drive up to 100nF capacitive loads stably in unity-gain configuration without external compensation, thanks to its C-Load™ architecture. This capability is verified across –40°C to 125°C and eliminates the need for output isolation resistors in ADC driver or filter applications. Performance remains stable with 100nF loads at all supply voltages from 1.8V to 5.25V.
Does the LTC6259IMS#TRPBF support true ground-sensing input operation?
Yes, the LTC6259IMS#TRPBF supports true ground-sensing: its input common-mode range extends to V– – 0.1V, allowing it to accurately amplify signals referenced to ground even when V– = 0V. Combined with rail-to-rail output swing to within 30mV of V–, this enables zero-referenced signal chains in single-supply systems - critical for pH, thermocouple, and bridge sensor interfaces.
What is the shutdown behavior of the LTC6259IMS#TRPBF output stage?
When the SHDN pin is pulled low (≤0.6V relative to V–), the LTC6259IMS#TRPBF output stages enter a high-impedance state - neither sourcing nor sinking current. The output voltage floats, preserving external circuit bias points. This behavior is confirmed across temperature and supply voltage, with leakage ≤100nA in shutdown, ensuring no unintended loading of downstream circuitry.
How does the EMI rejection ratio of the LTC6259IMS#TRPBF improve system robustness?
The LTC6259IMS#TRPBF provides 45dB EMI rejection ratio at 1GHz, measured as 20log(100mV/ΔVOS) under –10dBm RF injection. This hardens the amplifier against RF rectification in automotive or industrial settings, preventing erroneous offset shifts that could corrupt sensor readings or trigger false alarms - a key differentiator versus standard op amps lacking EMI-hardened input structures.
Is the LTC6259IMS#TRPBF pin-compatible with other members of the LTC6258/LTC6259/LTC6260 family?
No - the LTC6259IMS#TRPBF uses a 10-lead MSOP package with dedicated SHDN and NC pins, while LTC6258 (single) and LTC6260 (quad) use different pinouts and package types (e.g., 6-lead TSOT-23, 16-lead MSOP). Pin compatibility exists only within same-channel-count variants sharing identical packages (e.g., LTC6259ITS8#TRPBF in 8-lead TSOT-23), not across the family's package matrix.
