ADS1625IPAPT

Analog To Digital Converters (ADC) Overview

The ADS1625IPAPT is a single-channel, 18-bit analog-to-digital converter (ADC) from Texas Instruments. It utilizes a delta-sigma architecture and supports a sampling rate of 1.25 MSPS. The device features a parallel interface and accepts differential inputs. It operates with an analog supply voltage ranging from 4.75 V to 5.25 V and a digital supply voltage between 2.7 V and 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 93 dB, a differential nonlinearity (DNL) of +/- 0.5 LSB, and an integral nonlinearity (INL) of 3.5 LSB. The component includes an internal reference and is housed in a 64-lead HTQFP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and temperature rating match the design requirements. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement. Check for any recent lifecycle notices or obsolescence warnings directly from Texas Instruments to ensure long-term availability for production.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate speed and high resolution is required for single-channel applications. Compare DNL and INL specifications against system error budgets to ensure adequate linearity. Verify that the parallel interface timing constraints are compatible with the target microcontroller or DSP processor capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS1625 series of high-performance ADCs. It shares the same HTQFP-64 package form factor with other devices in the family but differs in resolution and sampling speed. It is distinct from lower-resolution variants like the ADS1605 or higher-resolution sigma-delta ADCs such as the ADS1274.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible substitutes within the same package may include other members of the ADS16xx family, provided the resolution and sampling rate meet the application needs. Verify electrical compatibility carefully, as differences in power consumption and interface timing may require circuit adjustments.
