Save your time with great and updated Eagle library from SparkFun

If you like designing PCB’s with Eagle CAD software this Eagle library may save you tons of time. It has many great footprints that are popular but not included in standard Eagle library like RGB through-hole LED, 16×2 LCD, Relays, RCA Jack, 3.5mm Audio Jack and more. Check out full list which is updating time to time. Also if you’re new to Eagle don’t forget to check Eagle Tutorials for fast start.

Eagle CAD PCB footprints for audio processors TDA7313 and TDA7315

TDA7313 and TDA7315 are digital controlled audio processors that can be used in applications where digital control of audio is needed. TDA7313 and TDA7315 are are pretty same just TDA7313 is more complex by hawing 3 stereo input channels and two outputs (front and rare). Both chips have volume control (step=1.25dB), tone (bass and treble) balance, independent faders for each output processors. Also there are loudness functionality. TDA7313 and TDA7315 have low distortion, low noise, that makes them ideal for quality audio applications for car audio and Hi-FI systems.   Both chips can be controlled by MCU via I2C(TWI) protocol. This makes easy to interface microcontrollers with additional features like LCD, buttons. Or simply control directly from PC using RS232 or other interface. Both chips can be found in DIP or SO packages. Here are Eagle libraries of both digital audio processors that I have made. I have …

AD9288 Protel Footprint

The AD9288 is a dual 8-bit monolithic sampling analog-to-digital converter with on-chip track-and-hold circuits and is optimized for low cost, low power, small size and ease of use. The product operates at a 100 MSPS conversion rate with outstanding dynamic performance over its full operating range. Each channel can be operated independently. The ADC requires only a single 3 V (2.7 V to 3.6 V) power supply and an encode clock for full-performance operation. No external reference or driver components are required for many applications. The digital outputs are TTL/CMOS compatible and a separate output power supply pin supports interfacing with 3.3 V or 2.5 V logic. The encode input is TTL/CMOS compatible and the 8-bit digital outputs can be operated from +3 V (2.5 V to 3.6 V) supplies. User selectable options are available to offer a combination of power down modes, digital data formats and digital data timing …

LPC229x protel library

The LPC2292 microcontrollers are based on a 16-bit/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 pct. with minimal performance penalty. With their 144-pin LQFP144 package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, 2/4 (LPC2292) advanced CAN channels, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications as well as medical systems and fault-tolerant maintenance buses. The number of available GPIOs ranges from 76 (with external memory) through 112 (single-chip). With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as …
