Product Overview
The ADS1113 is a Texas Instruments 16-bit I2C ADC in the Signal Chain category. It provides one differential or one single-ended analog input and reports no missing codes at 16-bit resolution. The device comparison data lists a maximum sample rate of 860 SPS, with programmable rates of 8, 16, 32, 64, 128, 250, 475, and 860 SPS and a -10% to +10% data-rate variation across all rates.
The converter operates from a 2.0 V to 5.5 V supply. Its ADC scaling range is ±0.256 V to ±6.144 V for VIN = V(AINP) - V(AINN), while recommended absolute analog input voltage is GND to VDD. The ADS1113 has no PGA and no comparator, so designs should account for the fixed device capability described in the device comparison table.
Package options include RUG X2QFN-10 at 1.50 mm x 2.00 mm, DYN SOT-10 at 2.90 mm x 2.80 mm, and DGS VSSOP-10 at 3.00 mm x 4.90 mm. The pin data identifies ADDR for I2C target address selection, SCL and SDA with pullup resistors to VDD, VDD with a 0.1 µF decoupling capacitor to GND, and no-connect pins 2, 6, and 7 that may be left floating or connected to GND.

Procurement Notes
When requesting a quote for ADS1113, 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.
FAQ
What resolution does the ADS1113 provide?
The ADS1113 provides 16-bit resolution with no missing codes. This resolution is listed in the extracted electrical characteristics and applies to the device as a 16-bit I2C ADC.
What input channel configuration does ADS1113 support?
The ADS1113 supports one differential input or one single-ended input. The analog input pins identified for ADS1113 are AIN0 on pin 4 and AIN1 on pin 5.
What supply voltage range is recommended for ADS1113?
The recommended operating supply range for ADS1113 is 2.0 V to 5.5 V from VDD to GND. The absolute maximum power-supply voltage rating is -0.3 V to 7 V.
