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.

Texas Instruments INA126PA Single SP Instrumented Amplifier, 18-36 V, 8-Pin, 9.81 mm L x 6.35 mm W x 4.57 mm H (Pack of 2), 6.35 millimeters Width, 9.81 millimeters Length, Volts (Pack of 2)

Model: INA126PA   |    Mpn: INA126PA   |    PartNumber: INA126PA   |   Asin: B06X6G2KFJ

The Ina126 and Ina2126 are precision instrumentation amplifiers for accurate, low noise differential signal acquisition. Their two-couples-amp design provides excellent performance with very low quiescent current (175 a/channel). this, combined with a wide operating voltage range of +/-1.35V to +/-18V, makes them ideal for portable instrumentation and data acquisition systems. Gain can be set from 5V/V to 10000V/V with a single external resistor. Laser trimmed input circuitry provides low offset voltage (250 v max), low offset voltage drift (3 v/ C max) and excellent common-mode rejection.

Features

  • Single version and low input bias current: 25Na max
  • Low quiescent current: 175A/channel
  • Wide supply range: +/-1.35V to +/-18V
  • Low offset voltage: 250 v max

ON SEMICONDUCTOR LM833NG IC, AUDIO OP-AMP, 15MHZ, DIP-8 (Pack of 10)

 PartNumber: LM833NG   |   Asin: B00MMYC3GG

The LM833 is a dual general purpose operational amplifier designed with particular emphasis on performance in audio systems. This dual amplifier IC utilizes new circuit and processing techniques to deliver low noise, high speed and wide bandwidth without increasing external components or decreasing stability. The LM833 is internally compensated for all closed loop gains and is therefore optimized for all preamp and high level stages in PCM and HiFi systems. The LM833NG is pin-for-pin compatible with industry standard dual operational amplifiers.

Features

  • Wide dynamiic range: >140dB
  • Low Input noise voltage: 4.5nV/ Hz
  • High Slew Rate: 7 V/ s (typ); 5V/ s (Min)
  • High Gain Bandwidth: 15MHz (typ); 10MHz (Min)
  • Wide Power Bandwidth: 120KHz

1-600MHz RF Signal Power Meter Logarithmic Detector -74dBm to 18dBm Radio Frequency Detection

 Ean: 0654936014572   |    PartNumber: 9687283011   |   Asin: B07B6M2768

The detector is is used for RF signal power detection of frequency range between 1MHZ and 600MHZ. It can detect a rf signal of power from -74dBm to 18dBm, and convert the RF signal into a DC voltage output. The higher radio frequency signal range or power is, the higher output voltage will be; output voltage is proportional to logarithm of input signal range. Widely used for RF signal detection, signal power measurement, environment field strength detection, can also be used as a part of automatic gain control and automatic level control. It can be made into 1mw ~ 1kw RF power meter after appropriate transformation. Specifications: Working Frequency: 1MHZ---600MHZ Measuring Power: -74dBm to +18dBm Output Voltage: 0---2.5V Detection Slope: 25mV/dBm (typical) Input Impedance: 50ohm Power Supply Voltage: 6-15V RF Input Connector: SMA-female OUT: Detection Output VCC: DC Power Supply Package Includes: 1 x RF Logarithmic Detector
