Frequently Asked Questions
What is the quiescent current of the LTC6258HDC#TRMPBF and why does it matter for battery-powered circuits?
The LTC6258HDC#TRMPBF draws only 23 µA of quiescent current per channel, making it one of the lowest-power op-amps in its class. This allows a single CR2032 coin cell to power the amplifier for months, which is critical in IoT sensors, wearables, and remote data loggers where battery replacement is costly or impractical.
What supply voltage range does the LTC6258HDC#TRMPBF support, and can it run from a single 3.3 V rail?
Yes. The LTC6258HDC#TRMPBF operates from a single supply of 1.8 V to 5.5 V, or a split supply up to ±2.75 V. Running from a single 3.3 V rail is well within specification, making it directly compatible with most microcontroller I/O levels and low-voltage ADC reference requirements.
How does the CMRR of 95 dB (typical) affect signal integrity in differential measurement applications?
A 95 dB typical CMRR means common-mode noise appearing on both inputs is attenuated by a factor of roughly 56,000 at the output. This level of rejection is essential for bridge sensor amplifiers, electrochemical cells, and temperature measurement circuits where ground-loop interference and 50 Hz/60 Hz pickup would otherwise corrupt millivolt-level signals.
What package does LTC6258HDC#TRMPBF use and what are its dimensions?
The LTC6258HDC#TRMPBF is housed in a 6-lead DFN (2 mm x 2 mm) package with an exposed thermal pad. This footprint is approximately 4 mm², which is suitable for densely packed PCBs in hearing-aid modules, medical patches, and miniaturized wireless sensor nodes where board area is at a premium.
When is LTC6258HDC#TRMPBF a better choice than a standard CMOS op-amp operating at higher current?
Whenever the quiescent budget for the analog front-end is below 50 µA total, the LTC6258HDC#TRMPBF at 23 µA is the right choice. Standard CMOS op-amps with comparable 1.3 MHz bandwidth typically draw 100 µA to 500 µA, which would reduce battery life by 5× to 20× in duty-cycled systems sampling every few seconds.
