Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADS1220IPWR is a precise 24-bit analog-to-digital converter (ADC). The multiple integrated features can reduce system costs and decrease the number of components in small sensor signal measurement applications. The ADS1220IPWR features two differential inputs or four single-ended inputs implemented through an input multiplexer (MUX), a low-noise programmable gain amplifier (PGA), two programmable excitation current sources, a voltage reference, an oscillator, a low-side switch, and a precision temperature sensor.

The ADS1220IPWR has the following main features:

Low current: As low as 120μA in duty cycle mode (typical value

Wide power supply voltage range: 2.3V to 5.5V

Programmable gain: 1V/V to 128V/V

Programmable data rate: up to 2kSPS

Up to 20-bit effective resolution

A single-period stable digital filter is adopted at 20SPS

Achieve harmonic suppression at 50Hz and 60Hz

Two differential inputs or four single-ended inputs

Double-matching programmable current source

10μA to 1.5mA

Integrated 2.048V reference voltage: drift 5ppm/°C (typical value)

Integrated 2% precise oscillator

Integrated temperature sensor: Accuracy 0.5°C (typical value)

Interface compatible with SPI (Mode 1)

The ADS1220IPWR is packaged in a 16-pin TSSOP and operates within a temperature range of -40°C to 125°C. It is widely applied in the following scenarios:

Temperature sensor measurement

Thermistor

Thermocouple

Resistive temperature detector (RTD)

2-wire, 3-wire or 4-wire system types

Resistance bridge sensor measurement

Pressure sensor

Stress gauge

Weighing instrument

Portable instrument

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.
