Digital Switches Go Analog
Pericom Semiconductor is breaking into the analog market with a new series of switches and multiplexers.
Pericom Semiconductor Corporation has introduced an additional family of seven analog multiplexers and switches. The company claims that these products feature improved performance over pin-compatible sole-source offerings. Housed in extremely small packaging, (for space-constrained mobile and handheld computing applications,) Pericom has branded the family as "SOTiny"
The low-voltage, low on-resistance family of devices provide users with minimum distortion and high-fidelity signal routing for such end-products as PDAs, cellular phones, GPS, and satellite systems. Pericom's new SPDT and SPST switches are implemented in low-power CMOS, hopefully resulting in long battery life.
Key Features of SOTiny Analog Switches
- Low on-resistance for maximum signal transfer and low distortion (7 ohms with a 5V supply; 12 ohms with a 3V supply; and 0.5 ohm resistance flatness.
- Wide power supply operation (single 1.65V to 5V supply; low current drain: 1 microampere (max.).
- Isolation and unwanted signal rejection: off isolation -80dB at 1MHz; crosstalk -80dB at 1MHz
Depending on functionality, prices for Pericom's analog multiplexers and switches range from $0.29 to $0.35 for 5,000 pieces. Currently in production, these devices are available in two to three weeks.
