STMicroelectronics (NYSE NYSE
See: New York Stock Exchange : STM (Scanning Tunneling Microscope) A microscope that can image down to the atomic level. An STM uses a piezoelectric tube with a tiny sharp tip at the end that is moved within nanometers of the object being sampled. ) has introduced a low distortion analog switch for signal routing in devices such as mobile phones, PDAs, GPS and CD-ROMs.
The STG3157CTR See click-through rate. single-pole double-throw (SPDT SPDT Single Pole, Double Throw
SPDT Single Point Diamond Turning (precision lathe used in optical fabrication)
SPDT Shadow Page Directory Table ) analog switch is housed in an extremely small SOT323 6-lead surface-mount package, also known as an 'SOTiny' package, so it can be used in applications where space is at a premium.
The part is designed to operate from 1.65V to 5.5V of V(CC), making it flexible enough to work in a wide range of portable applications. Maximum quiescent supply current is 1uA at T(A) (ambient temperature of 25 (degree)C).
The low On resistance of the device, of less than 9(OMEGA) at a V(CC) of 3.3V, minimizes signal distortion enabling high-fidelity signal routing. The part also offers excellent isolation and unwanted signal rejection, with Off isolation figures of -57dB and cross-talk of -54dB, both measured at 10MHz.
The STG3157CTR also offers a high switching speed of 0.8ns (max) at V(CC) of 3V.
The part has 'break before make' enable circuitry to ensure that it doesn't create any audible pops or clicks during transitions.
The STG3157CTR's inputs and output are protected against static discharge, giving them ESD (1) (Electronic Software Distribution) Distributing new software and upgrades via the network rather than individual installations on each machine.
