Description

Decoupling capacitors for VCC and PVCC. Two 1µF capacitors are enough for

proper decoupling of TS4601B. X5R dielectric and 10V rating voltage is

recommended to minimize ΔC/ΔV when VCC= 5V.

Must be placed as close as possible to the TS4601B to minimize parasitic

inductance and resistance.

Capacitor for internal negative power supply operation. X5R dielectric and 10V

rating voltage is recommended to minimize ΔC/ΔV when VCC= 5V.

Must be placed as close as possible to the TS4601B to minimize parasitic

inductance and resistance.

CSS

2.2µF

Filtering capacitor for internal negative power supply. X5R dielectric and 10V

rating voltage is recommended to minimize ΔC/ΔV when VCC = 5V.

Cin

Cin = -2---π----Z---1-i--n----F----c-

Input coupling capacitor that forms with Zin, a first order high pass filter with a

-3dB cut-off frequency FC. Zin is 12kΩ typical and independent of the gain

setting.

For example FC = 13Hz, Cin = 1µF and for FC = 6Hz, Cin = 2.2µF

Cout

0.8nF to 100nF

Output capacitor of 0.8nF minimum to 100nF maximum. This capacitor is

mandatory for operation of the TS4601B.

Rout

12Ω min.

Output resistor in series with the TS4601B output. This 12Ω minimum resistor

is mandatory for operation of the TS4601B.
