GX1220 100% Replacement for ADS1220 for Smart Temperature Transmitter

Intelligent temperature transmitter is an indispensable tool in industrial automation, which greatly improves the efficiency and quality of industrial production. Intelligent temperature transmitter is a device that can automatically collect, process and output temperature signals, which adopts advanced sensor technology and data processing technology to realize real-time monitoring and precise control of temperature.

 

This kind of equipment can not only improve the accuracy and stability of temperature measurement, but also realize remote monitoring and automatic control, which greatly improves the efficiency and quality of industrial production. This mainly depends on the resolution, sampling frequency, accuracy and linearity of the analog-to-digital converter, now GX1220 can 100% replace ADS1220 for intelligent temperature transmitter, so that the project to reduce certain R & D costs and provide technical support throughout.

 

In modern industrial production, precise temperature control is to ensure product quality and productivity of the key factors, the GX1220 is a high-precision 24-bit ADC, the chip has a flexible input multiplexer (MUX) through the low-noise, programmable gain amplifier (PGA), the bias voltage of each channel, the two programmable excitation current source, the voltage reference source, the oscillator, low-side switch and the precision temperature sensor three differential or five single-ended inputs.

 

The GX1220 is capable of performing conversions at data rates up to 3710 SPS. at ≤20 SPS, the digital filter provides 50Hz or 60Hz rejection for noisy industrial applications, making the GX1220 ideally suited for applications that measure signals from small sensors such as Resistance Temperature Detectors (RTDs), thermocouples, thermistors, and resistive bridge sensors. the GX1220 features the following :

- Wide power supply range: 2.7 V to 5.25 V

- Programmable gain: 1 V/ to 128 V/

- Programmable data rate: up to 3.7 kSPS

- Dual matched programmable current source: 10uA to 1.5mA

- SPI-compatible interface

- Available in QFN-16 or TSSOP-16 packages

- Available in QFN-16 or TSSOP-16 packages for -40°C to +125°C operating temperature range
