ADS7828EB/2K5G4 Equivalent & Substitute Parts

Part Overview

The ADS7828EB/2K5G4 is a 12-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring 8-channel input capability with I2C interface. This device features a Successive Approximation Register (SAR) architecture with integrated multiplexer and sample-and-hold functionality, operating across a wide supply voltage range of 2.7V to 5.25V for both analog and digital domains.

The ADS7828EB/2K5G4 is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADS7828EB/2K5G4 is determined by the following core parameters:

• 12-bit resolution
• 8-channel input configuration
• 50 kSPS sampling rate
• I2C digital interface
• SAR architecture with integrated multiplexer and sample-and-hold
• 16-TSSOP package form factor
• Surface mount mounting type
• Operating temperature range of -40°C to 85°C
• RoHS3 compliance

The substitute parts identified below maintain these critical parameters. Variations in input type configuration (Pseudo-Differential versus Differential/Single Ended), supply voltage ranges, moisture sensitivity levels, and product status are noted but do not preclude functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

ADS7828EB/2K5 is the manufacturer-recommended substitute. This part maintains active product status and offers improved moisture sensitivity characteristics (MSL 1 versus MSL 2). The extended supply voltage range (2.7V ~ 5.25V) provides additional design flexibility compared to the original part. Input type differs (Pseudo-Differential versus Differential/Single Ended), which may require circuit topology evaluation for specific applications.

ADS7828E/250 and ADS7828E/2K5 are parametric equivalents with active product status. Both maintain the original input type configuration (Differential, Single Ended) and supply voltage specifications. These parts offer superior moisture sensitivity ratings (MSL 1) and are suitable for applications requiring direct functional replacement with identical electrical characteristics.

ADS7828EIPWRQ1 is an automotive-grade variant qualified to AEC-Q100 standards. This part is appropriate for automotive and mission-critical applications requiring automotive-grade qualification. Moisture sensitivity level matches the original part (MSL 2). All other electrical and mechanical parameters align with the original specification.

All substitute parts are ROHS3 compliant and maintain the same operating temperature range, package form factor, and core functional architecture as the discontinued ADS7828EB/2K5G4.

Frequently Asked Questions (FAQ)

Q: Can ADS7828EB/2K5 be used as a direct replacement for ADS7828EB/2K5G4?

A: Yes. The ADS7828EB/2K5 maintains all critical functional parameters including 12-bit resolution, 8-channel input, 50 kSPS sampling rate, I2C interface, SAR architecture, and 16-TSSOP package. The primary difference is input type configuration (Pseudo-Differential versus Differential/Single Ended). Circuit topology should be evaluated to confirm compatibility with your specific input signal conditioning requirements.

Q: What is the difference between Pseudo-Differential and Differential/Single Ended input types?

A: Pseudo-Differential inputs reference all channels to a common ground, while Differential/Single Ended inputs allow true differential measurement between channel pairs or single-ended measurement to ground. The ADS7828EB/2K5 (Pseudo-Differential) is suitable for applications where all input signals share a common reference. The ADS7828E/250 and ADS7828E/2K5 (Differential/Single Ended) provide greater flexibility for mixed-signal input configurations.

Q: Is the ADS7828EIPWRQ1 suitable for non-automotive applications?

A: Yes. The ADS7828EIPWRQ1 is an automotive-qualified variant that exceeds standard industrial specifications. It can be used in any application where the original ADS7828EB/2K5G4 was specified. The AEC-Q100 qualification provides additional reliability assurance for mission-critical applications.

Q: What does MSL (Moisture Sensitivity Level) mean for component selection?

A: MSL indicates the maximum time a component can be stored in ambient conditions before soldering. MSL 1 (Unlimited) allows indefinite storage, while MSL 2 (1 Year) requires soldering within one year of packaging. For long-term inventory management, parts with MSL 1 rating (ADS7828EB/2K5, ADS7828E/250, ADS7828E/2K5) offer extended shelf life.

Q: Are all substitute parts available in the same packaging options?

A: All substitute parts are supplied in 16-TSSOP surface mount package. Packaging options (Cut Tape and Digi-Reel) are available for ADS7828EB/2K5, ADS7828E/250, ADS7828E/2K5, and ADS7828EIPWRQ1. Verify current packaging availability with your component supplier.

Q: What is the supply voltage range difference between ADS7828EB/2K5 and the original part?

A: The ADS7828EB/2K5 supports 2.7V ~ 5.25V for both analog and digital supplies, compared to the original part's 2.7V ~ 3.6V and 5V discrete levels. This extended range provides improved compatibility with 3.3V and intermediate supply voltages, reducing the need for voltage regulation in some applications.
