The MC33204D from onsemi is a quad-channel, general-purpose operational amplifier designed for low-voltage rail-to-rail operation. Housed in a 14-SOIC package, this IC operates over a wide supply voltage range of 1.8V to 12V, making it versatile for both battery-powered and industrial applications. With a 2.2 MHz gain bandwidth product and a 1V/µs slew rate, it balances speed and power efficiency, drawing 900µA per channel (3.6mA total for all four amplifiers). Its rail-to-rail input/output capability ensures maximum dynamic range in low-voltage systems, while the 80 mA output current per channel supports moderate load-driving requirements.
The MC33204D is a cost-effective, space-saving solution for low-voltage, multi-channel analog designs. Its rail-to-rail operation, moderate bandwidth, and low power consumption make it a pragmatic choice for battery-operated and industrial systems where component count and supply flexibility are critical. While now obsolete, its legacy design remains relevant for legacy repairs or low-complexity applications requiring reliable performance without cutting-edge specs. Engineers should evaluate modern alternatives for new designs but may still leverage this IC for its proven balance of simplicity and functionality.
