APPLICATION NOTES Sise 7 www.corebai.com CBM6001-CBM6002-CBM6004 OPERATION INSTRUCTION CBM6001 family series op amps are unity-gain stable and suitable for a wide range of general-purpose applications. The small footprints of the CBM6001 family packages save space on printed circuit boards and enable the design of smaller electronic products. Power Supply Bypassing and Board Layout CBM6001 family series operates from a single 1.8V to 6V supply or dual ±0.9V to ±3V supplies. For best performance, a 0.1µF ceramic capacitor should be placed close to the VDD pin in single supply operation. For dual supply operation, both VDD and VSS supplies should be bypassed to ground with separate 0.1µF ceramic capacitors. Low Supply Current The low supply current (typical 75µA per channel) of CBM6001 family will help to maximize battery life. They are ideal for battery powered systems. Operating Voltage CBM6001 family operates under wide input supply voltage (1.8V to 6V). In addition, all temperature specifications apply from -40℃ to +125℃. Most behavior remains unchanged throughout the full operating voltage range. These guarantees ensure operation throughout the single Li-Ion battery lifetime. Rail-to-Rail Input The input common-mode range of CBM6001 family extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V). This is achieved by using complementary input stage. For normal operation, inputs should be limited to this range. Rail-to-Rail Output Rail-to-Rail output swing provides maximum possible dynamic range at the output. This is particularly important when operating in low supply voltages. The output voltage of CBM6001 family can typically swing to less than 10mV from supply rail in light resistive loads (>100kΩ), and 60mV of supply rail in moderate resistive loads (10kΩ). Capacitive Load Tolerance The CBM6001 family is optimized for bandwidth and speed, not for driving capacitive loads. Output capacitance will create a pole in the amplifier’s feedback path, leading to excessive peaking and potential oscillation. If dealing with load capacitance is a requirement of the application, the two strategies to consider are (1) using a small resistor in series with the amplifier’s output and the load capacitance and (2) reducing the bandwidth of the amplifier’s feedback loop by increasing the overall noise gain. Figure 2 shows a unity gain follower using the series resistor strategy. The resistor isolates the output from the capacitance and, more importantly, creates a zero in the feedback path that compensates for the pole created by the output capacitance. 8 www.corebai.com CBM6001-CBM6002-CBM6004 OPERATION INSTRUCTION Figure 2. Indirectly Driving a Capacitive Load Using Isolation Resistor The bigger the RISO resistor value, the more stable VOUT will be. However, if there is a resistive load RL in parallel with the capacitive load, a voltage divider (proportional to RISO/RL) is formed, this will result in a gain error. The circuit in Figure 3 is an improvement to the one in Figure 2. RF provides the DC accuracy by feed-forward the VIN to RL. CF and RISO serve to counteract the loss of phase margin by feeding the high frequency component of the output signal back to the amplifier’s inverting input, thereby preserving the phase margin in the overall feedback loop. Capacitive drive can be increased by increasing the value of CF. This in turn will slow down the pulse response. Figure 3.

It is useful as a computational amplifier in making a differential to single-end conversion or in rejecting a common mode signal. Figure 4. shown the differential amplifier using CBM6001 family. Figure 4. Differential Amplifier 锨῜ = 锨῜ = If the resistor ratios are equal (i.e. R1=R3 and R2=R4), then Low Pass Active Filter The low pass active filter is shown in Figure 5. The DC gain is defined by –R2/R1. The filter has a -20dB/decade roll-off after its corner frequency ƒC=1/(2πR3C1). Figure 5.

The amplifier in Figure 6 is a high input impedance differential amplifier with gain of R2/R1. The two differential voltage followers assure the high input impedance of the amplifier. Figure 6.
