The MAX4740ETE+ is a quad SPDT audio switch in 16 pin TQFN package. It is a low on-resistance, low supply current and high power supply rejection ratio (PSRR) device. This analogue switch operates from single 1.6V to 5.5V supply and it is configured to route audio signals. The MAX4740 is pin to pin compatible with the STMicroelectronics quad SPDT STG3699 analogue switch. Switching logic is controlled by two control bits (CB1 and CB2). The device has low power supply current of 0.3μA which increases battery life. Logic inputs accept up to +5.5V regardless of supply voltage.
Total harmonic distortion is 0.08%
Operating temperature range from -40°C to 85°C
High PSRR is -60dB reduces supply noise
-68dB typical crosstalk at f = 100KHz and -64dB off isolation at f = 100KHz
Maximum on-resistance is 0.90 ohm at TA = +25°C
Maximum on-resistance flatness is 0.72ohm at TA = +25°C
Off leakage current is 0.1μA and on-leakage current is 0.1μA
