programmable gain amplifier (PGA)
The IP is a programmable gain amplifier (PGA), which consists of single ended amplifier, input and output switches, 14-selectable gain paths, and other control logic. The L7SPGA4B10G, operating with 5.0V analog power supply and 1.5V digital power supply, consumes 6.0mW power.
36V 1.5A PWM Driver for 3-Phase BLDC Motor
This IP is an intergrated three-phase BLDC motor drvier for home appliance, cooling fans, and other general-purpose motor control applications. The intergrated protections improve the system robustness and reliabilty.
40mW Headphone Amplifier with Class-G
Headphone amplifierwith Class-G drvies 40mW of power into 32 ohm load. This IP supports capless amplifer architecture, and maximize battery life with Class G.
High slew rate low power buffer amplifier
Low power and high slew rate CMOS rail to rail input/output op-amp in substitution for output buffer amplifier of conventional driver IC, is proposed. It is realized to add the output stage of class-AB in conventional op-amplifier to the newly designed control stage of class-B. Thus, it has the characteristics of low p..
2.6W Class-D Audio Amplifier
This IP is a highly efficient filter-free class-D audio amplifier of delivering 2.6W of continuous average power to a 4Ω from 5.5V supply in a bridge tied load (BTL) with less than 1% THD+N. It provides thermal and short circuit protection.
