Description
The AD22650 is a 3-Vrms cap-less stereo line
driver. The device is ideal for single supply
electronics. Cap-less design can eliminate output
dc-blocking capacitors for better low frequency
response and save cost.
The AD22650 is capable of delivering 3-Vrms
output into a 2.5kΩload with 5V supply. The gain
settings can be set by users from 1V/V to 10V/V
externally. The AD22650 has internal and external
under voltage protection to prevent POP noise.
Build-in shutdown control and de-pop control
sequence also help AD22650 to be a pop-less
device.
The AD22650 is available in a 14-pin TSSOP
package.

Application Information
Line Driver Amplifiers Operation
A conventional inverting line-driver amplifier always requires an output dc-blocking capacitor and a
bypass capacitor, see Figure 1. DC blocking capacitors are large in size and cost a lot. It also restricts
the output low frequency response. POP will occur if the charge and discharge processes on output

to VDD/2.
For a cap-less line driver, see figure 2, a negative supply voltage (-VDD) is produced by the integrated
charge-pump, and feeds to line driver’s negative supply instead of ground. The positive input can
directly connect to ground without a CBYPASS, and VOUT is biased at ground which can eliminate the
output dc-blocking capacitors. The output voltage swing is doubled compared to conventional amplifiers.

External Under-Voltage Protection
The external under-voltage protection is used to mute the line-driver before any input voltage change to
generate a POP. The threshold of UVP pin is designed to 1.25V. By using a resistor divider, users can
decide the UVP level and hysteresis level. The levels can be obtained by following equations:
VUVP = (1.25V − 6µA × R13) × (R11 + R12) / R12
Hysteresis = 5µA × R13 × (R11 + R12) / R12
With the condition R13 >> (R11 // R12).
For example, to obtain VUVP=2.67V, Hysteresis=0.37V, R11=1.5kΩ, R12=1kΩ, R13=30kΩ.

Charge-Pump Operation
The charge-pump is used to generate a negative supply voltage to supply to line-driver. It needs two
external capacitors, CFLY and CPVSS, for normal operation, see figure 4 (a). The operation can be
analyzed with two phase. In phase I, see figure 4 (b), CFLY is charged to PVDD, and in phase II, see
figure 4 (c), the charges on CFLY are shared with CPVSS, that makes PVSS a negative voltage. After an
adequate clock cycles, PVSS will be equaled to –PVDD. Low ESR capacitors are recommended, and
the typical value of CFLY and CPVSS is 1μF. A smaller capacitance can be used, but the maximum output
voltage may be reduced.

Enable Function
The enable function is used to reduce power consumption while the device is not in use. When a logic
low is applied to this pin, the overall circuits are turned off. Line driver output and PVSS are pulled to
ground. When a logic high is applied to enable pin, the PVSS is started to build-up and line driver output
signal is released after about 0.5ms typically.
Decoupling Capacitors
A low ESR power supply decoupling capacitor is required for better performance. The capacitor should
place as close to chip as possible, the value is typically 1μF. For filtering low frequency noise signals, a
10μF or greater capacitor placed near the chip is recommended.
Input Blocking Capacitors (CIN)
An input blocking capacitor is required to block the dc voltage of the audio source and allows the input
to bias at a proper dc level for optimum operation. The input capacitor and input resistor (RI) form a
high-pass filter with the corner frequency determined as following equation:

The values of RI and RF must be chosen with consideration of stability, frequency response and noise.
The recommended value of RI is in the range from 1kΩ to 47kΩ, and RF is from 4.7kΩ to 100kΩ for. The
gain is in the range from -1V/V to -10V/V for inverting configuration. Table 1 lists the recommended

Over-Temperature Protection
AD22650 provide an over-temperature protection to limit the junction temperature to 150℃. As junction
temperature exceeds 150℃, internal thermal sensor will turn off the drivers immediately. The drivers will
turn on again if the junction temperature is smaller than 130℃. A 20℃ hysteresis is designed to lower
the average junction temperature during continuous thermal overload conditions, increasing lifetime of
the chip.
