Chandler: Low-Power, Small Form-Factor Op Amps From Microchip Help To Extend Battery Life

  • Low quiescent current of 45 microamperes at 1 MHz
  • Space-saving SC-70 and SOT-23 packages
  • Low operating voltage and enhanced performance across the entire voltage range
  • Support Microchip eXtreme Low-Power PIC MCUs to extend battery life

Microchip announces the MCP6401/2/4 operational amplifiers, which add to Microchip’s general-purpose Op amp portfolio by providing lower power consumption in small packages. Featuring quiescent current of just 45 microamperes with a Gain Bandwidth Product (GBWP) of 1 MHz, the MCP6401/2/4 Op amps complement Microchip’s eXtreme Low Power PIC microcontrollers (MCUs), helping to extend battery life in a variety of applications which include music players, appliances and gaming consoles in the consumer sector; industrial barcode scanners and gas meters; automotive signal conditioning for proximity and tyre-pressure measurement sensors; and medical applications such as glucometers and portable patient-monitoring devices, among others.

Additional features include a maximum offset voltage of 4.5 mV and a supply-voltage range of 1.8V to 6V over the extended temperature range of -40ºC to +125ºC.  The Op amps are unity gain stable and feature Rail-to-Rail input and output operation for better performance across the entire voltage range.

The MCP6401/1U/1R are available in 5-pin SC-70 or SOT-23 packages, whilst the MCP6402 is offered in 8-pin SOIC or 2mm x 3mm TDFN packages, and the MCP6404, in 14-pin SOIC or TSSOP.
