Product Overview
The ADS1015 is a Texas Instruments Signal_Chain 12-bit I2C ADC with no missing codes. It provides 2 differential or 4 single-ended analog input channels and includes a programmable gain amplifier and comparator, supporting compact measurement interfaces where an I2C-connected converter is required.
Conversion data rates are programmable at 128, 250, 490, 920, 1600, 2400, and 3300 SPS, with ±10% variation across all data rates. The device supports a full-scale input voltage range from ±0.256 to ±6.144 V for ADC scaling, while the recommended absolute analog input voltage range is GND to VDD.
The ADS1015 operates from a 2.0 to 5.5 V supply over -40 to +125 °C ambient temperature. Package options include RUG X2QFN-10 1.5mm x 2mm, DYN SOT-10 2.9mm x 2.8mm, and DGS VSSOP-10 3mm x 4.9mm. I2C operation supports fast-mode and high-speed-mode SCL ranges, and the ADDR pin provides 4 target-address selections.

Procurement Notes
When requesting a quote for ADS1015, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
