Applications
The MCP6479-E/ST is well-suited for sensor signal conditioning, active filter design, and data acquisition front-end amplification in portable and industrial electronics. Its 3 MHz bandwidth and rail-to-rail operation make it a practical choice for audio processing, battery-powered instrumentation, and precision measurement systems that require 4 amplifier channels in a single TSSOP-14 package. The extended temperature rating also qualifies it for automotive sensor interfaces and outdoor industrial monitoring equipment.

Frequently Asked Questions
What bandwidth and CMRR does MCP6479-E/ST offer for precision sensor signal conditioning?
The MCP6479-E/ST provides a 3 MHz gain-bandwidth product and a typical common-mode rejection ratio (CMRR) of 76 dB, with a minimum CMRR of 60 dB. These specifications make it suitable for precision sensor signal conditioning applications where noise rejection and adequate bandwidth are both required, such as pressure sensor interfaces, temperature sensor amplifiers, and low-frequency data acquisition front ends.
For a 4-channel active filter design, how does MCP6479-E/ST reduce component count and board space?
MCP6479-E/ST integrates 4 independent op-amp channels into a single TSSOP-14 package, eliminating the need for 4 separate single-channel devices. This integration reduces board space significantly, as the 14-pin TSSOP package occupies less than 5 mm x 4.4 mm. For active filter designs requiring 4 filter stages at up to 3 MHz bandwidth, this quad op-amp reduces BOM cost and PCB area compared to using discrete single or dual op-amp packages.
Which temperature range does MCP6479-E/ST support, and what applications does this unlock?
The E-grade temperature suffix on MCP6479-E/ST indicates operation from -40°C to +125°C. This extended temperature range qualifies the device for automotive sensor amplification, outdoor industrial monitoring, and HVAC control systems where junction temperatures may routinely exceed commercial-grade limits of 0°C to +70°C. The 3 MHz bandwidth and 76 dB CMRR are maintained across this entire temperature range.
How does MCP6479-E/ST compare to a dual-channel op-amp like MCP6472 when 4 amplifier channels are needed?
When a design requires 4 amplifier channels, MCP6479-E/ST provides all 4 channels in a single TSSOP-14 package versus using 2 units of a dual op-amp like MCP6472. This halves the component count, reduces PCB footprint, and simplifies routing by eliminating a second device and its decoupling capacitors. Both share the 3 MHz bandwidth and rail-to-rail I/O, but the quad MCP6479-E/ST is more cost-effective per channel at high volumes.
