ADS1259BIPW

Overview

The ADS1259BIPW is a low-noise, 24-bit analog-to-digital converter (ADC) from Texas Instruments, utilizing sigma-delta architecture. It features a single differential input channel and an SPI interface with a maximum sampling rate of 14.4 kS/s. The device operates on a 4.75 V to 5.25 V analog supply and a 2.7 V to 5.25 V digital supply. Key electrical specifications include an integral nonlinearity (INL) of 0.0003% FSR and a typical power consumption of 13 mW. It supports both external and internal reference types and includes built-in 50/60 Hz rejection capabilities. The component is housed in a TSSOP-20 package and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrated programmable gain amplifier and low-drift reference buffer for high-precision signal conditioning
• Built-in digital filter providing selectable 50 Hz and 60 Hz line frequency rejection
• Low-power operation suitable for battery-supplied measurement systems

Applications

• Industrial process control and field transmitter signal acquisition
• High-resolution weighing scales and load cell interfaces
• Medical instrumentation requiring precise physiological signal monitoring

Procurement Notes

Verify the specific suffix 'IPW' against the manufacturer's official datasheet to confirm the TSSOP-20 package variant and industrial temperature rating. Ensure compatibility with system voltage levels and SPI timing requirements before integration. Cross-reference the part number with authorized distributors to validate authenticity and current production status.

Selection Notes

Select this component when a single-channel, high-resolution conversion is required without multiplexing multiple inputs. Compare against the ADS1258 for multi-channel needs or the ADS1259BIPWR if reel packaging is preferred over tube packaging. Evaluate the trade-off between the 14.4 kS/s speed and noise performance based on application bandwidth requirements.

Part Context

This device belongs to the ADS1259 family of precision data converters designed for sensor applications. It shares architectural similarities with other members like the ADS1259IPWR but differs in packaging configuration. The IPW suffix specifically denotes the TSSOP-20 surface-mount package intended for board-level integration.

Replacement Considerations

ADS1259IPWR serves as a functional equivalent with identical electrical characteristics, differing only in tape-and-reel packaging instead of tube.
