PIN DESCRIPTIONS Descriptions of the pins are listed in Table 3-1.
MCP660/1/2/3/4/5/9 3.1 Analog Outputs 3.4 Chip Select Digital Input (CS) The analog output pins (VOUT) are low-impedance voltage sources. The input (CS) is a CMOS, Schmitt-triggered input that places the part into a Low Power mode of operation. 3.2 3.5 Analog Inputs Exposed Thermal Pad (EP) The non-inverting and inverting inputs (VIN+, VIN-, …) are high-impedance CMOS inputs with low bias currents.
MCP660/1/2/3/4/5/9 4.0 APPLICATIONS The MCP660/1/2/3/4/5/9 family is manufactured using the Microchip state-of-the-art CMOS process. It is designed for low-cost, low-power and high-speed applications. Its low supply voltage, low quiescent current and wide bandwidth make the MCP660/1/2/3/4/5/9 ideal for battery-powered applications. 4.1 When implemented as shown, resistors R1 and R2 also limit the current through D1 and D2. VDD V1 Input 4.1.
MCP660/1/2/3/4/5/9 4.2 Rail-to-Rail Output 4.2.1 Figure 4-5 shows the power calculations used for a single op amp: MAXIMUM OUTPUT VOLTAGE The Maximum Output Voltage (see Figure 2-16 and Figure 2-17) describes the output range for a given load. For example, the output voltage swings to within 50 mV of the negative rail with a 1 k load tied to VDD/2. 4.2.2 OUTPUT CURRENT Figure 4-4 shows the possible combinations of output voltage (VOUT) and output current (IOUT), when VDD = 5.5V.
MCP660/1/2/3/4/5/9 The power derating across temperature for an op amp in a particular package can be easily calculated (assuming equal power dissipations): EQUATION 4-5: POAmax TJmax – TA n JA Where: TJmax = absolute max. junction temperature Several techniques are available to reduce TJA for a given POAmax: • Lower JA - Use another package - PCB layout (ground plane, etc.) - Heat sinks and air flow • Reduce POAmax - Increase RL - Limit IOUT (using RSER) - Decrease VDD Improving Stability 4.4.
MCP660/1/2/3/4/5/9 Figure 4-8 shows an op amp circuit that represents non-inverting amplifiers (VM is a DC voltage and VP is the input) or inverting amplifiers (VP is a DC voltage and VM is the input). The capacitances CN and CG represent the total capacitance at the input pins; they include the op amp’s Common mode input capacitance (CCM), board parasitic capacitance and any capacitor placed in parallel.

MCP660/1/2/3/4/5/9 4.5 MCP663 and MCP665 Chip Select 4.7 High Speed PCB Layout The MCP663 is a single amplifier with Chip Select (CS). When CS is pulled high, the supply current drops to 1 µA (typical) and flows through the CS pin to VSS. When this happens, the amplifier output is put into a high-impedance state. By pulling CS low, the amplifier is enabled. The CS pin has an internal 5 M (typical) pulldown resistor connected to VSS, so it will go low if the CS pin is left floating.
MCP660/1/2/3/4/5/9 4.8 Typical Applications 4.8.1 4.8.3 50 LINE DRIVER Figure 4-10 shows the MCP661 driving a 50 line. The large output current (e.g., see Figure 2-18) makes it possible to drive a back-matched line (RM2, the 50 line and the 50 load at the far end) to more than ±2V (the load at the far end sees ±1V). It is worth mentioning that the 50 line and the 50 load at the far end together can be modeled as a simple 50 resistor to ground. -2.5V RG 301 FIGURE 4-10: RM2 49.
