Microchip unveils the MCP6401/2/4/ operational amplifiers (op amps) that offer low power consumption and flaunt smaller package sizes. These devices target power demands in consumer, industrial, automotive and medical applications.

The MCP6401/2/4/, which comes in packages as small as SC-70 and SOT-23, features quiescent current of 45µA with a gain bandwidth product of 1MHz.

The key features offered are maximum offset voltage of ± 4.5mV; supply-voltage range of 1.8V-6V over the temperature range of -40C to +125C; unity gain stable; and rail-to-rail input and output operation.

The devices are available in both volume and sample quantities today. The MCP6401/1U/1R in 5-pin SC-70, SOT-23 packages are available at Rs.12.14 ($0.26) each in 10,000-unit quantities; the MCP6402 in 8-pin SOIC, 2mmx3mm TDFN are pegged at Rs.14.94 ($0.32) each in 10,000-unit quantities; and the MCP6404 in 14-pin SOIC, TSSOP are priced at Rs.20.08 ($0.43) each in 10,000-unit quantities. Microchip's Active Filter Demo Board Kit (MCP6XXXDM-FLTR, Rs.3,035.38 ($65)) and MCP6XXX evaluation boards (Rs.1,400.95 ($30) each) support the op amps.
