This is a headphone amplifier project for audio digital-to-analog converters (DACs) with differential voltage outputs. This circuit converts the differential voltage output of the DAC to a single-ended, ground-referenced signal and provides the additional current necessary for...

ROHM's amps feature a power package HTSOP-J8 to achieve high output power ROHM's BD783xxEFJ-M series includes 6 dB to 26 dB voltage gain products. These Class AB amps have no requirements for care about EMI noise. Adopting a power package HTSOP-J8 achieves high output power. The low...

The project presented here is a photodiode amplifier for visible light. The output voltage of the circuit increases linearly with light intensity. Low-cost BPW34 photodiode is used as a light sensor and OPA381 op-amp as an amplifier. OPA381 is a transimpedance amplifier that converts...

Good news for all audio enthusiasts: we are proud to present yet another all-analog circuit developed entirely in house. Despite the simple design of this audio power amp with just one pair of transistors in the output stage, Q-Watt can deliver over 200 quality watts into 4 ohms with...

The TSC2010, TSC2011 and TSC2012 are precision bidirectional current sense amplifiers. They can sense the current thanks to a shunt resistor over a wide range of common-mode voltages, from - 20 to + 70 V, whatever the supply voltage is. They are available with an amplifier gain of 20V/V...

The EVAL_AUDAMP24 e-mode GaN HEMT-based evaluation board from Infineon Technologies is a 2-channel, 225W/ch (4Ω at ±43V) or 250 W/ch (8Ω at ±63V) half-bridge class D audio power amplifier for high-end Hi-Fi audio systems. This evaluation board demonstrates how to use the IGT40R070D1...

ROHM recently announced the AEC-Q100 qualified 2.8W output Class AB monaural speaker amplifiers the BD783xxEFJ-M series (BD78306EFJ-M, BD78310EFJ-M and BD78326EFJ-M) ideal for instrument clusters – used in vehicles equipped with autonomous driving and ADAS. In recent years,...

An open source universal audio amplifier called ‘U-AMP‘ @ GmanModz, that is available on GitHub: Using what I learned getting digital audio working on each systems, I set out on a new project I would call “U-AMP” (Universal-Amp). This would be ONE pcb which has the features of...
