ADS1015LIDGSR

Analog To Digital Converters (ADC) Overview

The ADS1015LIDGSR is a precision, low-power, 12-bit analog-to-digital converter (ADC) from the Texas Instruments ADS101xL series. It features four single-ended or two differential input channels, an internal programmable gain amplifier (PGA), and a digital comparator. The device operates on a supply voltage range of 2.0 V to 3.6 V with a maximum sampling rate of 3.3 kSPS. It utilizes an I²C interface compatible with 1.8-V bus voltages and includes an internal low-drift voltage reference and oscillator. The component is housed in a 10-pin VSSOP package and supports an operating temperature range from –40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-bit delta-sigma ADC core with an internal voltage reference and oscillator for high-precision signal conversion.
• Includes a programmable gain amplifier (PGA) allowing configurable full-scale input ranges from ±0.256 V to ±6.144 V.
• Features a digital comparator with ALERT/RDY output pin support for under- and overvoltage detection or conversion-ready signaling.
• Supports I²C communication with four pin-selectable addresses and compatibility with 1.8-V bus logic levels.

Analog To Digital Converters (ADC) Applications

• Supply-voltage monitoring in general systems
• Current measurement using shunt resistors
• Temperature measurement via thermistors or sensor ICs

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix IDGSR corresponds to the VSSOP-10 package and tape-and-reel packaging configuration. Confirm that the L-series designation indicates 1.8-V I²C bus voltage support, which differs from standard ADS1015 variants. Ensure the procurement source provides the official Texas Instruments datasheet SBASAV7 for final electrical characteristic validation before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when space-constrained designs require a 12-bit resolution with multiple input channels. The ADS1015LIDGSR is suitable for applications needing PGA flexibility and digital comparison without external components. Consider the 2.0 V to 3.6 V supply limit; if higher voltages are required, the standard ADS1015 family should be evaluated instead. Verify I²C address conflicts if multiple devices share the bus.

Analog To Digital Converters (ADC) Part Context

The ADS1015LIDGSR belongs to the ADS101xL family, which extends the standard ADS101x series with enhanced I²C compatibility for lower voltage buses. Unlike the standard ADS1015, the 'L' variant supports 1.8-V logic levels independent of the supply voltage. This makes it distinct from the ADS1015AQDGSRQ1, which is automotive-grade and supports up to 5.5 V.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS1015IDGSR is a functional substitute but lacks 1.8-V I²C bus voltage support. The ADS1015LIDGSR is the direct equivalent within the same package. For automotive applications, the ADS1015AQDGSRQ1 offers similar functionality with extended voltage tolerance and AEC-Q100 qualification.
