MCP6404-E/ST

MCP6404-E/ST Description

The MCP6404-E/ST from Microchip Technology is a general-purpose operational amplifier (op-amp) featuring four independent channels in a compact 14-TSSOP surface-mount package. Designed for low-power applications, it operates over a wide supply voltage range of 1.8V to 6V, making it versatile for both battery-powered and industrial systems. With a gain bandwidth product (GBWP) of 1 MHz and a slew rate of 0.5V/µs, it delivers stable performance for signal conditioning, filtering, and amplification tasks. The device exhibits ultra-low input bias current (1 pA) and moderate input offset voltage (800 µV), ensuring precision in high-impedance sensor interfaces.

MCP6404-E/ST Features

• Low Power Consumption: Only 45µA per channel (180µA total for 4 channels), ideal for energy-sensitive designs.
• Rail-to-Rail Input/Output: Maximizes dynamic range in low-voltage applications.
• High Output Drive: 15 mA per channel enables direct driving of small loads.
• Robust Packaging: TSSOP-14 offers space efficiency for dense PCB layouts.
• Environmental Compliance: ROHS3 and REACH compliant, with MSL 1 (Unlimited) moisture sensitivity for extended shelf life.
• Wide Temperature Range: Suitable for industrial and automotive environments.

MCP6404-E/ST Applications

• Portable Electronics: Sensor signal conditioning in wearables and IoT devices due to low power and small footprint.
• Battery-Powered Systems: Energy-efficient amplification in medical devices (e.g., glucose monitors).
• Industrial Control: Analog front-ends for pressure/ temperature sensors, leveraging its wide supply range.
• Consumer Audio: Preamplifiers and active filters where low noise and stability are critical.
• Automotive Modules: Signal buffering in infotainment or ADAS systems, benefiting from its robustness.

Conclusion of MCP6404-E/ST

The MCP6404-E/ST stands out as a cost-effective, multi-channel op-amp combining low power, precision, and versatility. Its 1.8V–6V operation and rail-to-rail performance make it superior to older-generation op-amps limited to higher voltages. Compared to similar models, its ultra-low bias current and compact package are decisive for space-constrained, high-impedance designs. Whether for portable, industrial, or automotive applications, this op-amp delivers reliable performance while meeting stringent environmental standards.
