What are the key features of OPA2695IDG4?
- Dual current-feedback amplifier architecture delivers flat gain-bandwidth performance ideal for high-frequency video and RF signal amplification on ±6 V supply rails
- Operates from ±6 V dual supply or 12 V single supply in a compact 8-pin SOIC package, simplifying multi-channel amplifier board layout
- 56 dB typical common-mode rejection ratio with integrated frequency compensation reduces external component count in wideband differential signal chain designs
What is OPA2695IDG4 used for?
The OPA2695IDG4 suits wideband signal amplification in video distribution amplifiers, cable drivers, and RF test equipment where two high-speed channels are required in a minimal footprint. Its current-feedback topology maintains consistent bandwidth across gain settings, making it ideal for fixed-gain amplifier stages in communications and instrumentation systems. The ±6 V dual-supply operation suits precision analog signal chains in professional audio, test, and measurement equipment requiring headroom above single-supply designs.

Frequently Asked Questions
Why use a current-feedback amplifier like OPA2695IDG4 instead of a voltage-feedback op-amp in a wideband video line driver?
Current-feedback amplifiers like the OPA2695IDG4 maintain nearly constant bandwidth as gain is varied, unlike voltage-feedback amplifiers whose bandwidth drops proportionally with gain. For video line drivers operating at gains of 2 to 10 over bandwidths of 100 MHz or more, this means the OPA2695IDG4 can drive a 75 Ω back-terminated cable with flat frequency response where a voltage-feedback amplifier would suffer excessive roll-off at higher gains.
What supply voltage does OPA2695IDG4 require, and can it run from a single 12 V automotive or industrial rail?
The OPA2695IDG4 is rated for ±6 V dual-supply operation, which is equivalent to a 12 V single-supply configuration. In single-supply mode it can run directly from a 12 V automotive or industrial rail when the inputs are biased to mid-supply, making it compatible with in-vehicle infotainment amplifier chains and 12 V industrial signal conditioning designs without an additional negative supply rail.
How does the OPA2695IDG4 compare to OPA695 single-channel in a space-constrained 2-channel amplifier design?
The OPA2695IDG4 integrates 2 current-feedback amplifier channels in an 8-pin SOIC package measuring approximately 5 mm x 4 mm, compared to using two individual OPA695 single-channel devices which would require 2 separate SO-8 packages and roughly double the PCB footprint. The dual integration also eliminates one set of bypass capacitors and reduces routing complexity, lowering total BOM cost per channel in high-volume video and RF amplifier designs.
What is the input offset voltage specification of OPA2695IDG4, and how does it affect DC-coupled signal chains?
The OPA2695IDG4 specifies a maximum input offset voltage of 4500 µV (4.5 mV). In DC-coupled amplifier stages with a gain of 10, this offset can produce up to 45 mV of output error, which may clip the headroom in precision DC measurement systems. For applications where DC accuracy below 1 mV is required, a precision voltage-feedback op-amp with lower offset should be considered, while OPA2695IDG4 is better suited for AC-coupled wideband video and RF applications.
