MAX11335ATJ+T

Analog To Digital Converters (ADC) Overview

The MAX11335ATJ+T is a 12-bit, 4-channel successive approximation register (SAR) analog-to-digital converter (ADC) from the MAX11335–MAX11340 family. It operates at a sampling rate of 500ksps with a full-linear bandwidth of 500kHz. The device features ±1 LSB INL and DNL without missing codes, achieving a typical SNR of 72.3 dB and SINAD of 71.9 dB at 100kHz input frequency. Powered by a 2.35V to 3.6V supply, it consumes 4.2mW at 500ksps. Key features include SampleSet technology for programmable channel sequencing, internal averaging, an integrated FIFO, and external access to multiplexer outputs for post-mux signal conditioning.

• Industrial control systems
• Medical instrumentation
• Battery-powered instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the ATJ+ suffix indicates the TQFN-32 package and industrial temperature range (-40°C to +125°C). Confirm the 'T' suffix denotes tape-and-reel packaging. Ensure the specific part number matches the 4-channel variant (MAX11335) rather than the 8 or 16-channel derivatives within the same datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high linearity and low power are required for multi-channel applications. The 4-channel configuration suits systems needing fewer inputs than the 8 or 16-channel variants. Consider the external reference requirement and the need for SampleSet flexibility if complex channel sequencing is necessary. Verify that the source impedance meets the requirements for optimal SNR performance.

Analog To Digital Converters (ADC) Part Context

The MAX11335ATJ+T belongs to the MAX11335–MAX11340 series, which shares identical electrical characteristics but differs in channel count. The MAX11335 specifically provides 4 single-ended channels. Other family members include the 8-channel MAX11336/MAX11339 and the 16-channel MAX11337/MAX11340. All variants utilize the same 32-pin TQFN package and pinout structure.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes within the same family include MAX11336ATJ+T (8-channel) and MAX11337ATJ+T (16-channel), provided additional channels are acceptable. No other manufacturer cross-references are verified in the provided documentation.
