MCP6144-E/P Microchip

MCP6141/2/3/4 M 600 nA, Non-Unity Gain Rail-to-Rail Input/Output Op Amps Features Description Low Quiescent Current: 600 nA/Amplifier (typ.) The MCP6141/2/3/4 family of non-unity gain stable operational amplifiers (op amps) from Microchip Stable for gains of 10 V/V or higher Technology, Inc. operate with a single supply voltage Rail-to-Rail Input: -0.3V (min.) to V + 0.3V (max.) DD as low as 1.4V, while drawing less than 1 A (max.) of Rail-to-Rail Output: quiescent current per amplifier. These devices are also -V +10 mV (min.) to V -10 mV (max.) SS DD designed to support rail-to-rail input and output swing. Gain Bandwidth Product: 100 kHz (typ.) The MCP6141/2/3/4 op amps have a gain bandwidth Wide Supply Voltage Range: 1.4V to 5.5V (max.) product of 100 kHz (typ.) and are stable for gains of Available in Single, Dual and Quad 10V/V or higher. This specification makes these devices appropriate for battery-powered applications Chip Select (CS) with MCP6143 where higher frequency responses from the amplifier are required. Applications The MCP6141/2/3/4 family of op amps are offered in Toll Booth Tags single (MCP6141), single with a Chip Select (CS) fea- Wearable Products ture (MCP6143), dual (MCP6142) and quad Temperature Measurement (MCP6144) configurations.
