ADS1201UG4 Equivalent & Substitute Parts

Part Overview

The ADS1201UG4 is a 24-bit modulator IC from Texas Instruments designed for single-channel data acquisition applications with a 1 kHz sampling rate and serial data interface. The device operates on dual analog and digital supply voltages (4.75V to 5.25V) and is housed in a 16-SOIC surface mount package.

The ADS1201UG4 has been discontinued at DiGi Electronics. Locating equivalent or substitute components is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS1201UG4 is determined by the following critical parameters:

• Resolution and Sampling Rate: 24-bit resolution at 1 kHz sampling rate
• Channel Configuration: Single-channel operation
• Data Interface: Serial communication protocol
• Supply Voltage: Dual analog and digital supplies within 4.75V to 5.25V range
• Package Type: 16-SOIC surface mount package with 0.295" (7.50mm) width
• Operating Temperature: -40°C to 85°C range
• Compliance: ROHS3 compliance and MSL 2 rating

The ADS1201U is identified as a manufacturer-recommended substitute. Both parts share identical electrical specifications, channel configuration, resolution, sampling rate, data interface, supply voltage requirements, operating temperature range, and package specifications. The primary difference is packaging format (tube versus unspecified for the original part) and product status.

Parameter Comparison

Engineering Selection Recommendations

The ADS1201U is a direct functional equivalent to the ADS1201UG4. Both parts maintain identical electrical and mechanical specifications across all critical parameters including resolution, sampling rate, supply voltage, operating temperature range, and package configuration.

Selection between these parts should be based on availability and product status. The ADS1201UG4 is discontinued, while the ADS1201U carries a Last Time Buy status with 3600 units in stock. For new designs or production requiring this modulator specification, the ADS1201U is the appropriate selection. Both parts maintain ROHS3 compliance and equivalent moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can the ADS1201U directly replace the ADS1201UG4 in existing designs?

A: Yes. The ADS1201U is electrically and mechanically identical to the ADS1201UG4. Both parts feature 24-bit resolution, 1 kHz sampling rate, single-channel serial interface, identical supply voltage requirements (4.75V to 5.25V), matching operating temperature range (-40°C to 85°C), and the same 16-SOIC package configuration. No design modifications are required.

Q: What is the difference between the ADS1201UG4 and ADS1201U?

A: The primary difference is packaging format and product status. The ADS1201UG4 is discontinued at DiGi Electronics, while the ADS1201U is available in tube packaging with Last Time Buy status. All electrical and mechanical specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both the ADS1201UG4 and ADS1201U maintain ROHS3 compliance, REACH Unaffected status, and identical Moisture Sensitivity Level 2 (1 Year) ratings.

Q: What supply voltage does this modulator require?

A: The ADS1201UG4 and ADS1201U require dual analog and digital supply voltages within the range of 4.75V to 5.25V.

Q: Is the 16-SOIC package suitable for automated assembly?

A: Yes. The 16-SOIC package is a standard surface mount package with 0.295" (7.50mm) width, compatible with conventional pick-and-place and reflow soldering processes.
