Frequently Asked Questions
What supply voltage does the TLV2451CDBVTG4 support?
The TLV2451CDBVTG4 operates from dual supplies of ±3 V or a single supply of up to 6 V total. This flexibility makes it compatible with both 3.3 V single-supply microcontroller systems and dual ±2.5 V or ±3 V precision analog systems.
What does rail-to-rail input/output mean for the TLV2451CDBVTG4?
Rail-to-rail input means the common-mode input voltage can extend across the full supply range, while rail-to-rail output means the output swings within millivolts of both supply rails. Together these features maximize dynamic range and signal fidelity in low-voltage precision measurement applications.
What is the input offset voltage of the TLV2451CDBVTG4?
The TLV2451CDBVTG4 has a maximum input offset voltage of 2000 µV (2 mV). This level of offset is suitable for general-purpose signal conditioning, active filters, and buffer stages where moderate precision is required without the need for laser-trimmed or chopper-stabilized amplifiers.
Why is the ultra-low bias current of the TLV2451CDBVTG4 important?
The TLV2451CDBVTG4 has a maximum input bias current of 7 pA and a typical value of 5 pA. This extremely low bias current minimizes error voltage across high source impedances, making it essential for interfacing with photodiodes, electrochemical sensors, and high-value resistor networks where nanoamp-level leakage would cause measurement errors.
What package does the TLV2451CDBVTG4 come in and what is its footprint?
The TLV2451CDBVTG4 is housed in a 5-pin SOT-23 surface-mount package (R-PDSO-G5), one of the smallest available for op-amps. Its tiny footprint is ideal for miniaturized PCB designs in wearables, hearing aids, medical devices, and compact industrial sensors where board space is at a premium.
