AS21P2TLRQ Description

Short technical summary and product information.

The AS21P2TLRQ is a low voltage dual single-pole double-throw (SPDT) analog switch from STMicroelectronics, designed for precision signal routing in portable and battery-powered applications. It features a maximum on-resistance of 500mΩ, ensuring minimal signal attenuation. The device offers a -3dB bandwidth of 55MHz, making it suitable for high-speed analog and digital signals. Key electrical characteristics include a charge injection of 49pC, crosstalk of -72dB at 100kHz, and maximum switch times of 65ns (turn-on) and 40ns (turn-off). The supply voltage range is 1.65V to 4.3V, with a maximum supply current of 200nA. Power dissipation is rated at 1.12W, and propagation delay is 300ps typical.

 

The switch operates over a temperature range of -40°C to 85°C. It is housed in a 10-UFQFN package (10-QFN 1.8x1.4), with a height of 500µm, length of 1.9mm, and width of 1.5mm. The device is surface mountable and is supplied in Tape & Reel packaging. Break-before-make switching action is inherent, preventing momentary short circuits during channel transitions. The AS21P2TLRQ is suitable for applications such as audio signal routing, data acquisition systems, and analog multiplexing in battery-operated devices.
