Mingjiada Electronics Supply TI ADS1118IDGSR Low Power, 16Bit Analog To Digital Converter

[Shenzhen Mingjiada Electronics Co., Ltd.] As a trusted supplier of electronic components, we have been providing customers with genuine Texas Instruments (TI) chips, specifically the ADS1118IDGSR. This device is a precision analogue-to-digital converter (ADC) that integrates multiple advanced features, designed for applications requiring high precision, low power consumption, and compact size.

1. ADS1118IDGSR Product Description
The ADS1118IDGSR is a 16-bit Δ-Σ ADC with an integrated programmable gain amplifier (PGA), voltage reference, oscillator, and temperature sensor. At its core is a low-noise PGA and a high-precision Δ-Σ ADC, supporting data rates of up to 860 samples per second (SPS).
The ADS1118IDGSR offers 4 single-ended input channels or 2 differential input channels, with an input multiplexer (MUX) that can be flexibly configured as needed.
Notably, the ADS1118IDGSR integrates a high-precision temperature sensor internally, enabling environmental temperature measurement without external components, with an accuracy of ±2°C (typical). The ADS1118IDGSR is housed in a miniature VSSOP-10 package and communicates via a standard SPI-compatible interface, with its design specifically optimised for power-constrained and space-limited applications.
