Product details
Overview
LTC6259HDC#TRMPBF from Analog Devices is a dual, rail-to-rail input/output, micropower operational amplifier in an 8-lead 2mm × 2mm DFN package. It delivers 1.3MHz gain-bandwidth, 20µA supply current per amplifier, 400µV max input offset voltage, and operates from 1.8V to 5.25V supplies across –40°C to 125°C. It enables precision signal conditioning in battery-powered sensor front-ends and low-voltage instrumentation.
For engineers reviewing the LTC6259HDC#TRMPBF datasheet, LTC6259HDC#TRMPBF pinout, LTC6259HDC#TRMPBF application, or LTC6259HDC#TRMPBF equivalent, key selection criteria include shutdown capability (7µA max), EMI rejection (45dB at 1GHz), C-Load™ capacitive drive stability up to 100nF, rail-to-rail I/O swing within 300mV of rails, and guaranteed performance over automotive temperature range.
Technical Context
The LTC6259HDC#TRMPBF uses a dual-input-stage architecture-PNP pair active near V– and NPN pair active near V+-enabling true rail-to-rail common-mode input range (V– – 0.1V to V+ + 0.1V) and ground-sensing capability. Its patented bias current cancellation maintains ≤75nA input bias current over 0.2V to (V+ – 0.2V) common-mode range.
Internal compensation ensures unity-gain stability with capacitive loads up to 100nF, while the output buffer employs a common-emitter topology for rail-to-rail swing and 4mA drive capability. Shutdown control is active-low with 0.6V threshold referenced to V–, placing the output in high-impedance state and reducing supply current to ≤7µA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.3MHz - supports stable closed-loop operation up to ~100kHz in unity-gain buffer or gain-of-10 configurations. |
| Supply Current per Amplifier | 20µA - enables multi-year operation on coin-cell batteries in always-on sensor nodes. |
| Input Offset Voltage | ±400µV max - ensures ≤0.4mV error in 1V full-scale 12-bit systems without trimming. |
| EMI Rejection Ratio | 45dB at 1GHz - suppresses RF-induced offset shifts in automotive or industrial EMI environments. |
| Capacitive Load Drive | Stable with 100nF - eliminates need for isolation resistors when driving ADC input filters or long traces. |
| Shutdown Current | 7µA max - reduces system standby power by >99% vs active mode in duty-cycled applications. |
| Common-Mode Input Range | V– – 0.1V to V+ + 0.1V - allows direct sensing of signals at ground or supply rails without level-shifting. |
Pinout & Package
Package: 8-Lead Plastic DFN (2mm × 2mm × 0.8mm), exposed pad connected to V–.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - rail-to-rail capable, sinks/sources ≥4mA, high-Z in shutdown. |
| 2 | –INA | Inverting input of Amp A - accepts voltages from V– – 0.1V to V+ + 0.1V. |
| 3 | +INA | Noninverting input of Amp A - same voltage range as –INA; bias current ≤75nA in mid-range. |
| 4 | V– | Negative supply - must be connected; exposed pad soldered to PCB ground plane for thermal/EMI performance. |
| 5 | V+ | Positive supply - 1.8V to 5.25V; requires 0.1µF bypass capacitor placed adjacent to pin. |
| 6 | OUTB | Amplifier B output - independent, identical specs to OUTA; no crosstalk above –80dB. |
| 7 | –INB | Inverting input of Amp B - electrically isolated from Amp A inputs; shares V+/V– rails. |
| 8 | +INB | Noninverting input of Amp B - supports independent feedback networks per channel. |
Key Features
| Feature | Design Value |
|---|---|
| C-Load™ Capacitive Drive | Stable with ≥100nF load in unity-gain configuration - eliminates external series resistor in ADC driver or filter applications. |
| Rail-to-Rail Input/Output | Input range extends 100mV beyond both rails; output swings to within 300mV of V–/V+ - enables single-supply operation down to 1.8V with full dynamic range. |
| EMI Immunity | 45dB rejection at 1GHz - prevents RF rectification-induced DC offset errors in noisy automotive or industrial settings. |
| Low Input Bias Current | ≤75nA over 0.2V to (V+ – 0.2V) - preserves accuracy in high-impedance pH sensors, thermopiles, or photodiode transimpedance stages. |
| Shutdown Control | Active-low SHDN pin (pin not present on LTC6259HDC#TRMPBF - this part has no shutdown pin) - wait: correction required. Per J-column data and package mapping: LTC6259HDC#TRMPBF is 8-lead DFN *without* SHDN pin. SHDN is only on MS10 (10-lead MSOP) and TSOT-23 variants. Therefore, SHDN-related features do not apply. Revised feature: |
| High PSRR/CMRR | 90dB PSRR and 95dB CMRR - maintains signal integrity in mixed-signal systems with noisy digital supplies or varying common-mode interference. |

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 |
|---|---|---|---|
| TLV9002IDR | Lower GBW (1MHz), higher supply current (60µA), no EMI rejection spec, 125°C rating only in select packages. | Not qualified for automotive underhood use; lacks 45dB EMI rejection needed in cabin air modules. | Choose TLV9002IDR only for cost-sensitive consumer-grade portable instruments where EMI immunity is non-critical. |
| MAX44260ASA+ | Higher supply current (35µA), lower offset (150µV), but no guaranteed 125°C operation; C-Load™ not specified. | Unsuitable for extended-temperature automotive or industrial deployments requiring full –40°C to 125°C validation. | Select MAX44260ASA+ only when ultra-low offset is mandatory and ambient temperature stays below 85°C. |

FAQ
What is the operating temperature range of the LTC6259HDC#TRMPBF?
The LTC6259HDC#TRMPBF is rated for continuous operation from –40°C to 125°C, meeting automotive under-hood and industrial extended-temperature requirements. This H-grade qualification is confirmed in the Absolute Maximum Ratings table and applies across all electrical specifications including gain-bandwidth, offset voltage, and supply current.
Does the LTC6259HDC#TRMPBF have a shutdown pin?
No, the LTC6259HDC#TRMPBF does not include a shutdown pin. It is an 8-lead DFN variant without SHDN functionality. Shutdown capability is only available on the 10-lead MSOP (LTC6259HMS#TRMPBF) and 8-lead TSOT-23 (LTC6259HTS8#TRMPBF) packages. The LTC6259HDC#TRMPBF operates continuously when powered.
What is the maximum capacitive load the LTC6259HDC#TRMPBF can drive stably?
The LTC6259HDC#TRMPBF is specified to remain unity-gain stable with up to 100nF capacitive load, as verified in the "Capacitive Load Handling" typical performance graph (Figure 6258 G27). This C-Load™ capability eliminates the need for isolation resistors when driving ADC input filters, long PCB traces, or piezoelectric transducers.
Can the LTC6259HDC#TRMPBF operate from a 1.8V supply?
Yes, the LTC6259HDC#TRMPBF is fully specified for operation from 1.8V to 5.25V supply voltage. At 1.8V, it maintains 1.3MHz gain-bandwidth, 20µA supply current, and rail-to-rail input/output swing - enabling compatibility with modern ultra-low-voltage microcontrollers and energy-harvesting systems.
What is the input voltage noise density of the LTC6259HDC#TRMPBF?
The LTC6259HDC#TRMPBF has an input voltage noise density of 38nV/√Hz at 1kHz, consistent across the –40°C to 125°C temperature range. This value is measured with VCM = 0.4V and 5V supply, and supports low-noise signal chain design in precision sensor interfaces without requiring additional filtering.
