OPERATION INSTRUCTION  
Features  
Description  
Single-Supply Operation from +2.5V ~  
The CBM8051/1N(single), CBM8052/2N(dual),  
CBM8054(quad) are rail-to-rail output voltage  
feedback amplifiers offering ease of use and  
low cost. They have bandwidth and slew rate  
typically found in current feedback amplifiers.  
All have a wide input common-mode voltage  
range and output voltage swing, making them  
easy to use on single supplies as low as 2.5V.  
Despite being low cost, the CBM8051 series  
provide excellent overall performance. They  
offer wide bandwidth to 250MHz (G = +1)  
along with 0.1dB flatness out to 52MHz (G =  
+2) and offer a typical low power of  
2.8mA/amplifier.

The CBM8051 series is low distortion and  
fast settling make it ideal for buffering high  
speed A/D or D/A converters. The  
CBM8051/2N has a power-down disable  
feature that reduces the supply current to  
50µA. These features make the CBM8051/2N  
ideal for portable and battery-powered  
applications where size and power are critical.  
All are specified over the extended -40℃ to  
+125℃ temperature range.

Application Note  
Driving Capacitive Loads  
CBM805X series op amps are unity-gain stable and suitable for a wide range of general-  
purpose applications. The small footprints of the CBM805X series packages save space on  
printed circuit boards and enable the design of smaller electronic products.  
Power Supply Bypassing and Board Layout  
CBM805X series operates from a single 2.5V to 5.5V supply or dual ±1.25V to ±2.75V  
supplies. For best performance, a 0.1µF ceramic capacitor should be placed close to the VDD  
9
www.corebai.com  
CBM8051-52-53-54  
OPERATION INSTRUCTION  
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 2.8mA per channel) of CBM805X series will help to maximize  
battery life. They are ideal for battery powered systems  
Operating Voltage  
CBM805X series operate under wide input supply voltage (2.5V to 5.5V). In addition, all  
temperature specifications apply from -40℃ to +125℃. Most behavior remains unchanged  
throughout the full operating voltage range. These guarantees ensureoperation throughout the  
single Li-Ion battery lifetime  
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 CBM805X  
series can typically swing to less than 8mV from supply rail in light resistive loads (>1kΩ), and  
30mV of supply rail in moderate resistive loads (150Ω).  
Capacitive Load Tolerance  
The CBM805X 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.  
Figure 2. Indirectly Driving a Capacitive Load Using Isolation Resistor

CBM8051-52-53-54  
OPERATION INSTRUCTION  
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.

Differential amplifier  
The differential amplifier allows the subtraction of two input voltages or cancellation of a  
signal common the two inputs. 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 CBM805X.
