ON Semiconductor has introduced three low-resistance analog switches for portable and wireless audio applications. The parts are offered in lead-free thin QFN and DFN packages that require between 1.2 and 4.7 mm2 of board space. These 6-, 10-, and 16-pin high-performance audio analog switches are designed for high-current switching of an audio signal in applications with low operating voltages. The devices are suited for higher power audio applications that require low on-resistance (RON ) for improved power efficiency.
The NLAS3799MNR2G is a low-voltage, dual double pole-double throw (dual DPDT) switch. It achieves total harmonic distortion of 0.11% and an RON of 0.35-Ω. In addition, the it can operate with a 1.8-V input swing. It sells for $0.97 per unit in 10,000-unit quantities.
The NLAS5223MNR2G is a low-voltage, dual single pole-double throw (dual SPDT) switch that achieves total harmonic distortion of 0.12% and RON of 0.35-Ω. It's priced at $0.67 per unit in 10,000-unit quantities.
The NLAS5123MNR2G is a 1-Ω, single SPDT analog switch with 0.012 % total harmonic distortion and break before make capability. It costs $0.56 per unit in 10,000-unit quantities. For additional information or to order samples, visit www.onsemi.com.
