ADS1015QNKSRQ1

Analog To Digital Converters (ADC) Overview

The ADS1015QNKSRQ1 is a 12-bit, I2C-compatible analog-to-digital converter (ADC) from the ADS101x-Q1 family. It features four single-ended or two differential inputs via an internal multiplexer. The device integrates a programmable gain amplifier (PGA), a low-drift voltage reference, and an internal oscillator. It operates on a supply voltage of 2.0 V to 5.5 V with a maximum data rate of 3.3 kSPS. The component is housed in a 10-pin UQFN package (NKS) measuring 2 mm × 1.6 mm. It supports AEC-Q100 Grade 1 qualification for operation between –40°C and +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Confirm that the NKS package designation matches the required footprint dimensions. Ensure compliance with automotive functional safety documentation requirements if applicable to the design.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four analog input channels are required within a space-constrained automotive environment. The integrated PGA allows measurement of small signals without external amplification. Verify that the I2C interface speed and address configuration meet the system bus requirements.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS101x-Q1 series of ultra-small, low-power ADCs. It shares architectural similarities with the ADS1013-Q1 and ADS1014-Q1 but distinguishes itself through the inclusion of an input multiplexer for multiple channel measurements. The Q1 suffix indicates automotive qualification.

Analog To Digital Converters (ADC) FAQ

What is the maximum full-scale input voltage range?

The full-scale input voltage range can be configured by the PGA to values including ±6.144 V, ±4.096 V, ±2.048 V, ±1.024 V, ±0.512 V, or ±0.256 V.

How does the device handle power consumption during idle periods?

In single-shot mode, the ADC performs one conversion and then enters a power-down state, significantly reducing power consumption during idle periods.

Can an external voltage reference be used with this device?

No, the ADS1015-Q1 has an integrated voltage reference, and an external reference cannot be used with these devices.
