What are the key features of LTC6261HDC#TRPBF?
- Rail-to-rail input and output swing on ±2.625V to ±5.25V supply for maximum dynamic range
- Ultralow 0.05µA bias current at 25°C minimizes source loading in high-impedance sensor interfaces
- 90 dB typical CMRR with 70 dB minimum ensures accurate signal amplification in noisy automotive environments
- AEC-Q100 automotive-grade qualification in a compact 6-pin DFN package with exposed pad for thermal performance
What is LTC6261HDC#TRPBF used for?
The LTC6261HDC#TRPBF is engineered for automotive sensor signal conditioning where rail-to-rail I/O and low bias current are critical, such as in pressure sensor interfaces, battery management amplifiers, and infotainment signal chains operating from 3V to 5V rails. Its 90 dB CMRR makes it effective in rejecting common-mode noise on long automotive wiring harnesses. The compact 6-pin DFN package suits space-constrained ECU and body electronics designs requiring precision amplification across -40°C to +125°C temperature ranges.

Frequently Asked Questions
What bias current specification makes LTC6261HDC#TRPBF suitable for high-impedance automotive sensor interfaces?
The LTC6261HDC#TRPBF specifies a maximum bias current of 0.05µA at 25°C and 0.15µA over the full temperature range. This ultralow input current causes negligible voltage error even with source resistances above 1 MΩ, making it ideal for capacitive pressure sensors and resistive divider circuits in automotive ECUs where source impedances typically range from 100 kΩ to 10 MΩ.
How does the 90 dB CMRR of LTC6261HDC#TRPBF benefit automotive wiring harness applications?
The LTC6261HDC#TRPBF achieves 90 dB typical common-mode rejection ratio, meaning a 1V common-mode noise signal on the automotive harness produces less than 32µV of differential output error. This level of rejection effectively suppresses alternator ripple, ignition noise, and 12V bus transients that commonly appear on sensor lines running alongside power cables in vehicle wiring looms.
Which automotive temperature grade does LTC6261HDC#TRPBF meet and what junction temperature range does it cover?
The LTC6261HDC#TRPBF is an H-grade automotive component rated for operation from -40°C to +125°C junction temperature, consistent with AEC-Q100 Grade 1 qualification requirements. This range covers under-hood automotive environments where ambient temperatures can exceed 105°C, ensuring reliable amplifier performance in engine management and transmission control modules.
When is LTC6261HDC#TRPBF a better choice than a standard CMOS op-amp for a 5V single-supply automotive design?
LTC6261HDC#TRPBF outperforms standard CMOS op-amps in 5V automotive designs because its rail-to-rail output swings within millivolts of both supply rails, maximizing the usable output range from a ±2.625V to ±5.25V supply. In contrast, standard CMOS op-amps typically lose 100mV to 300mV headroom at each rail, reducing effective dynamic range for ADC-front-end and sensor amplifier applications operating on tight supply budgets.
