Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADS1115IDGSR is a 16-bit low-power precision analogue-to-digital converter (ADC) that is I2C-compatible and comes in a leadless VSSOP-10 package. The ADS1115IDGSR device features a low-drift voltage reference and oscillator. It also includes a programmable gain amplifier (PGA) and a digital comparator. In addition to these features, these devices offer a wide operating supply voltage range, making them ideal for power-constrained and space-constrained sensor measurement applications.

The ADS1115IDGSR device achieves a maximum data conversion rate of 860 samples per second (SPS). The PGA provides an input range from ±256mV to ±6.144V, enabling precise measurement of both small and large signals. The ADS1115IDGSR includes an input multiplexer (MUX) that supports dual differential input or quad single-ended input measurements. Digital comparators in the ADS1115IDGSR enable under-voltage and over-voltage detection.

Features: ADS1115IDGSR

16-bit high-precision ADC: Supports 860 SPS (samples per second), providing high-resolution signal conversion.

Programmable gain amplifier (PGA): Input range from ±256 mV to ±6.144 V, suitable for signals of varying amplitudes.  

Low-power design:  

Continuous mode current of only 150 μA, automatically enters low-power mode after a single conversion.  

Single-supply operation (2.0 V to 5.5 V), suitable for battery-powered devices.  

Flexible input configuration:

4 single-ended inputs or 2 differential inputs (ADS1115).

Built-in multiplexer (MUX) supports multi-channel switching.

Built-in comparator: Can be used for under-voltage/over-voltage detection, supports threshold-triggered interrupts.

• Portable instruments

• Battery voltage and current monitoring

• Temperature measurement systems

• Consumer electronics

• Factory automation and process control

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
