Frequently Asked Questions
What is the supply voltage range and input/output swing of the TLV9042IDDFR?
The TLV9042IDDFR operates from ±2.75V dual supply or 5.5V single supply, with rail-to-rail input and output (R-R I/O) capability. This means the input common-mode voltage and output voltage can swing from the negative supply rail to the positive supply rail, maximizing usable signal range in low-voltage single-supply applications.
How low is the bias current of the TLV9042IDDFR and why does it matter?
The TLV9042IDDFR has an exceptionally low maximum bias current of 0.000012µA (12pA) at 25°C. This ultra-low bias current is critical for high-impedance sensor applications such as photodiode amplifiers, pH meters, and capacitive sensors, where even small input currents can cause significant voltage errors when multiplied by large source impedances.
What is the CMRR of the TLV9042IDDFR?
The TLV9042IDDFR achieves a nominal common-mode rejection ratio (CMRR) of 89dB with a minimum of 75dB. High CMRR is essential for rejecting common-mode noise and interference in differential signal measurement applications. The voltage-feedback architecture with internal frequency compensation ensures stable operation across the full common-mode input range.
What package does the TLV9042IDDFR come in and how was it introduced?
The TLV9042IDDFR is packaged in an 8-pin SOT-23 (DDFR suffix) which is a miniature surface-mount package ideal for compact PCB designs. It was introduced on May 14, 2020 and has an estimated time on life (YTEOL) of 15 years, indicating long-term availability. The tape-and-reel packaging (R suffix) supports automated SMT assembly.
What are common applications for the TLV9042IDDFR dual op-amp?
Common applications include precision signal conditioning for resistive bridge sensors, photodiode current-to-voltage converters, active low-pass and band-pass filters, single-supply instrumentation amplifier stages, and battery-monitoring circuits in portable electronics. The dual-channel design allows implementing differential amplifier or Sallen-Key filter topologies within a single compact 8-pin SOT-23 package.
