MCP6281/2/3/4/5 450 μA, 5 MHz Rail to Rail Op Amp

MCP6281/2/3/4/5 General Description

The Microchip Technology Inc. MCP6281/2/3/4/5 family of operational amplifiers (op amps) provide wide bandwidth for the current. This family has a 5 MHz Gain Bandwidth Product (GBWP) and a 65° phase margin. This family also operates from a single supply voltage as low as 2.2V, while drawing 450 μA (typ.) quiescent current. Additionally, the MCP6281/2/3/4/5 supports rail-to-rail input and output swing, with a common mode input voltage range of VDD + 300 mV to VSS – 300 mV. This family of operational amplifiers is designed with Microchip’s advanced CMOS process.

The MCP6285 has a Chip Select (CS) input for dual op amps in an 8-pin package. This device is manufactured by cascading the two op amps (the output of op amp A connected to the non-inverting input of op amp B). The CS input puts the device in Low-power mode.

The MCP6281/2/3/4/5 family operates over the Extended Temperature Range of -40°C to +125°C. It also has a power supply range of 2.2V to 5.5V.

The LM7809 of three terminal positive regulators are available in the TO-220 package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

LM358 General Description

The LM358 series consists of two independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply  voltage.

Application areas include transducer amplifiers, dc gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems. For example, the LM158 series can be directly operated off of the standard +5V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±15V power supplies.

LM 358 Unique Characteristics:

• In the linear mode the input common-mode voltage range includes ground and the output voltage can also swing to ground, even though operated from only a single power supply voltage.
• The unity gain cross frequency is temperature compensated.
• The input bias current is also temperature compensated.

LM358 Features:

• Available in 8-Bump micro SMD chip sized package
• Internally frequency compensated for unity gain
• Large dc voltage gain: 100 dB
• Wide bandwidth (unity gain): 1 MHz (temperature compensated)
• Wide power supply range: Single supply: 3V to 32V or dual supplies: ±1.5V to ±16V
• Very low supply current drain (500 μA)— essentially independent of supply voltage
• Low input offset voltage: 2 mV
• Input common-mode voltage range includes ground
• Differential input voltage range equal to the power supply voltage
• Large output voltage swing
