ADS1110A7IDBVT

Analog To Digital Converters (ADC) Overview

The ADS1110A7IDBVT is a 16-bit, single-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device features an internal 2.048 V reference, enabling a differential input range of ±2.048 V. It supports I2C serial interface communication and includes a programmable gain amplifier (PGA) with selectable gains up to 8. Key electrical parameters include a maximum sampling rate of 128 S/s, integral nonlinearity (INL) of 6.5 LSB, and power consumption of 720 µW. The component is housed in a compact SOT-23-6 package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'A7' against the official datasheet to confirm the exact address configuration or variant specifications, as suffixes often denote unique pinout or addressing settings. Ensure the SOT-23-6 package compatibility matches the target PCB footprint. Cross-reference the manufacturer part number directly with Texas Instruments documentation to validate the current production status and environmental compliance details before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-resolution conversion is required in a minimal footprint. The internal 2.048 V reference simplifies design by eliminating external reference needs. Consider the 128 S/s maximum data rate and PGA capabilities for applications involving low-level signals. Verify that the I2C bus speed requirements align with the device's operational limits and that the operating temperature range covers the intended environment.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1110 family of precision ADCs from Texas Instruments. The family shares common core architectures but varies in package types, address configurations, and specific performance optimizations. The 'DBVT' suffix indicates the SOT-23-6 surface-mount package and tape-and-reel delivery method. Other variants in the series may offer different sampling rates or address codes while maintaining similar functional characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include ADS1110A0IDBVT, ADS1110A1IDBVT, ADS1110A4IDBVT, and ADS1110A5IDBVT. These parts share identical electrical specifications and pinouts but differ in I2C slave address configurations determined by the middle letter suffix. Verify address compatibility with the host microcontroller before substitution.
