What are the key features of LTC6253ITS8#TRMPBF?
- Rail-to-rail input and output swing on a 5.25 V single supply maximizes dynamic range in low-voltage automotive and portable signal conditioning circuits
- 105 dB typical common-mode rejection ratio (77 dB minimum) rejects power supply noise and ground offsets in sensor amplification applications
- Dual op-amp channels in a compact 8-pin TSOT-23 package reduce board footprint versus two discrete SOT-23-5 amplifiers while maintaining full automotive temperature qualification
What is LTC6253ITS8#TRMPBF used for?
The LTC6253ITS8#TRMPBF is designed for automotive sensor signal conditioning, battery cell voltage measurement, and precision instrumentation amplifier stages where a low-power dual op-amp with rail-to-rail I/O and high CMRR must fit within a compact TSOT-23 footprint. Its wide ±2.625 V or 5.25 V supply range and automotive qualification also make it suitable for current sense amplifier input stages, active filter circuits, and transducer interface conditioning in body electronics and chassis control modules.

Frequently Asked Questions
What common-mode rejection ratio does the LTC6253ITS8 guarantee, and why does that matter for automotive sensor interfaces?
The LTC6253ITS8#TRMPBF specifies a minimum CMRR of 77 dB and a typical CMRR of 105 dB. In an automotive environment with ground offset noise of up to 100 mV between ECU and sensor ground references, 77 dB CMRR attenuates that noise to less than 14 µV at the amplifier output, keeping common-mode interference well below the signal level for sensors with millivolt-range outputs such as shunt current sense resistors and bridge pressure transducers.
How does the rail-to-rail input and output capability of the LTC6253ITS8 expand usable signal range on a 5 V supply?
With rail-to-rail input and output on a 5.25 V single supply, the LTC6253ITS8 can amplify input signals that swing from 0 V to 5.25 V and produce output voltages across nearly the full supply range, typically within 50 mV of each rail. This utilizes the full 5.25 V dynamic range for ADC driving, compared to classical op-amps that may be limited to 1 V to 4 V output swing on the same supply, effectively reducing usable range by over 40%.
Is the LTC6253ITS8#TRMPBF suitable for use in automotive under-hood environments, and what temperature range does it cover?
Yes, the LTC6253ITS8#TRMPBF is automotive-qualified and operates over the extended industrial-to-automotive temperature range, typically -40°C to 125°C junction temperature. This covers under-hood ECU environments where ambient temperatures can reach 105°C with additional self-heating. The device also supports ±2.625 V dual-supply operation for bridge sensor conditioning in mixed-supply automotive systems.
When is a dual op-amp in TSOT-23-8 a better fit than two separate SOT-23-5 amplifiers for a compact PCB layout?
A dual amplifier in TSOT-23-8 occupies approximately 8 mm² including pad extensions, compared to roughly 14 mm² for two discrete SOT-23-5 devices placed side by side with required clearance spacing. In addition to saving 6 mm² of board area, the dual package shares a common bypass capacitor, reducing decoupling component count by 1. This matters on densely packed automotive sensor boards where every square millimeter of PCB space is contested by multiple analog and digital circuits.
