ADS1115 16-Bit ADC - 4 Channel with Programmable Gain Amplifier

Model: ADA1085   |    Mpn: ADA1085   |    Ean: 0711978445259   |    PartNumber: ADA1085   |   Asin: B00QIW4MGW

For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 16 bit converter.

The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1115's connected on a single 2-wire I2C bus for 16 single ended inputs.

To get you started, we have example code for both the Raspberry Pi (in our Adafruit Pi Python library) and Arduino (in our ADS1X15 Arduino library repository) Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.

Parts Express TL072ACP IC Dual J-FET Op-Amp 8 Pin DIP

 Ean: 0844632044021   |   Asin: B00CWEN8YW

The JFET-input operational amplifiers in the TL07x series are similar to the TL08x series, with low input bias and offset currents and fast slew rate. The low harmonic distortion and low noise make the TL07x series ideally suited for high-fidelity and audio preamplifier applications.

Features

  • Low Power Consumption
  • Wide Common-Mode and Differential Voltage Ranges
  • Low Input Bias and Offset Currents
  • Output Short-Circuit Protection
  • Low Total Harmonic Distortion: 0.003% Typ

Peachtree 220 amp (Gloss Black)

Model: 220Amp   |    Ean: 0703340620210   |   Asin: B0096SH74O

Now - More Power From Peachtree! The Peachtree220 has 220 watts per channel into 8 ohms and 400 watts per channel into 4 ohms! This new breed of Class D amplification samples many times that of the original modules making the 220 smooth and extended. Unlike Class D amps of the past, it produces room-shaking bass. The 220 has both balanced and unbalanced inputs and is 90% energy efficient. The novaPre preamplifier is the perfect complement to the Peachtree220 - in rosewood, high gloss black or cherry.

Features

  • Frequency Response: 65Hz-20kHz
  • Power Requirement: 20-150 watts
  • Tweeter: 1 soft dome
  • Woofer: 4 long excursion
