Frequently Asked Questions
What is the resolution and data rate of the ADS1112IDGST?
The ADS1112IDGST provides 16-bit resolution at a 15 samples-per-second (SPS) data rate. This high resolution makes it suitable for precision measurement applications such as industrial sensors and medical instrumentation where accurate analog-to-digital conversion is essential.
Does the ADS1112IDGST require an external voltage reference?
No, the ADS1112IDGST includes an integrated 2.048V internal voltage reference, eliminating the need for an external reference component. This simplifies circuit design, reduces BOM cost, and saves board space in compact applications.
What interface does the ADS1112IDGST use and how many devices can share the bus?
The ADS1112IDGST uses an I2C interface and supports four configurable I2C addresses, allowing up to four ADS1112 devices to share the same two-wire bus simultaneously. This is particularly useful in multi-channel sensing systems.
What are the typical applications for the ADS1112IDGST?
The ADS1112IDGST is commonly used in portable industrial instrumentation, medical monitoring equipment, environmental sensing, temperature measurement, pressure transducer interfaces, and battery-powered IoT data loggers where high-resolution ADC performance and low power consumption are required.
What package does the ADS1112IDGST come in and what is its supply voltage range?
The ADS1112IDGST is housed in a SOT-23-6 (DSBGA/SC-70 style) surface-mount package. It operates from a single supply voltage ranging from 2.7V to 5.5V, making it compatible with both 3.3V and 5V system designs.
