AS13704D
The ALFA AS13704 D consists of four current-controlled operational transconductance amplifiers OTA, each with differential inputs and a push-pull output. All amplifiers share common supplies, but operate independently. Linearizing diodes are provided at the inputs to reduce distortion and allow higher input levels. The result is a 10-dB signal-to¬-noise improvement referenced to 0.5 percent THD. SSOP-24.

AS16M1
The AS16M1 analog switch with serial digital interface offers 16 pairs individually controlled single-pole-change-over (SPCO) switches. All switches conduct equally in either direction and on-resistance (170Ω) is constant over the analog signal range. These CMOS switches can operate continuously with power supply +5V and switch input currents in any combination to output node (summing) or ground them. Upon power-up, all summing switches are off, grounding switches are on and the internal serial and parallel shift registers are reset to zero. The AS16M1 is controlled by a serial interface. The interface is compatible with the SPI interface standard. QFN-28.
