Replacement verdict
Compatible functional replacement candidate
The ADS8343EB/2K5G4 is a viable functional replacement candidate for the ADS8341E, sharing the same 16-bit SAR architecture, 4-channel differential input multiplexer, and SPI-compatible serial interface. Designers should validate the supply voltage range and package footprint against the target application before committing to the substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADS8341E | ADS8343EB/2K5G4 | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 16 bit | Both are 16-bit SAR ADCs, so resolution is equivalent and not a differentiator for substitutability. |
| Number of Input Channels | 4 single-ended / 2 differential | 4 single-ended / 2 differential | Channel count and configuration determine how many signals can be measured and whether differential inputs are available. |
| Sampling Rate | 100 kSPS | 100 kSPS | Maximum throughput affects the bandwidth of signals the ADC can digitize in an application. |
| Supply Voltage | 2.7 V to 5.25 V | 2.7 V to 5.25 V | Operating supply range determines compatibility with the system power rail and logic levels. |
| Interface Type | SPI-compatible serial | SPI-compatible serial | The digital interface must match the host controller to allow direct communication without glue logic. |
| Package / Mounting | SSOP-16, surface mount | SSOP-16, surface mount | Package and footprint must be compatible for a drop-in replacement on an existing PCB. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range confirms suitability for industrial and extended-environment applications. |
| Reference Input | External reference | External reference | Reference architecture affects accuracy, full-scale range, and the need for an external reference source. |

Frequently asked questions
What are the key differences between the ADS8341E and ADS8343EB/2K5G4?
The ADS8341E is a 16-bit, 4-channel successive-approximation ADC in a 16-pin SSOP package, while the ADS8343EB/2K5G4 is a 16-bit, 4-channel SAR ADC in a 16-pin TSSOP package supplied in tape-and-reel form (2K5 indicates 2500-unit reel). Both share similar resolution and channel count but differ in package type and ordering format.
Do the ADS8341E and ADS8343EB/2K5G4 have the same pin count and package footprint?
Both devices are offered in 16-pin packages, but the ADS8341E uses an SSOP (Shrink Small Outline Package) while the ADS8343EB/2K5G4 uses a TSSOP (Thin Shrink Small Outline Package). These are distinct package outlines with different body dimensions and lead pitches, so PCB land patterns are not interchangeable without verification against the respective datasheets.
Are the ADS8341E and ADS8343EB/2K5G4 functionally interchangeable in an existing design?
Direct substitution requires validation. Although both are 16-bit, 4-channel SAR ADCs, differences in package type, pinout details, and specified operating parameters must be confirmed against the official Texas Instruments datasheets for each device before any replacement is attempted.
What is the resolution and channel count of these ADCs?
Both the ADS8341E and ADS8343EB/2K5G4 are 16-bit analog-to-digital converters with 4 input channels, based on the successive-approximation register (SAR) architecture as documented in their respective Texas Instruments datasheets.
What does the "2K5G4" suffix indicate on the ADS8343EB/2K5G4?
The "2K5" portion denotes a tape-and-reel quantity of 2500 units, and "G4" is a Texas Instruments ordering suffix indicating Pb-free (RoHS-compliant) construction. This ordering format differs from the ADS8341E, which is specified as a tube or individual-part orderable.
Which package should be selected for a space-constrained design?
The ADS8343EB/2K5G4 uses a TSSOP package, which is generally thinner than the SSOP package used by the ADS8341E. Designers should compare the exact body dimensions and lead pitch from the official datasheets to determine which package best fits the available board area.
Can the ADS8341E be replaced by the ADS8343EB/2K5G4 in a production run?
Replacement requires confirming pinout compatibility, package land pattern compatibility, and electrical parameter equivalence using the official Texas Instruments datasheets for both devices. Because the package types differ (SSOP vs TSSOP), the PCB footprint must be revalidated before substituting one for the other.
