Product details
Overview
MAX1301AEUP+T from Maxim Integrated is a 16-bit, 4-channel (single-ended) or 2-channel (true differential), multirange successive-approximation ADC operating from a single +5V analog supply and a separate +2.7V to +5.25V digital I/O supply. It delivers up to 115ksps throughput, ±1.0 LSB INL (A-grade), ±16.5V overvoltage-tolerant inputs, and software-programmable input ranges including ±3 × VREF (±12.288V with internal 4.096V reference), used in industrial data-acquisition front-ends.
For engineers reviewing the MAX1301AEUP+T datasheet, MAX1301AEUP+T pinout, MAX1301AEUP+T application, or MAX1301AEUP+T equivalent, key selection considerations include its 20-pin TSSOP package, independent per-channel range programming, internal/external reference flexibility, fault-tolerant analog inputs, and SPI/QSPI/MICROWIRE-compatible serial interface for microcontroller integration.
Technical Context
The MAX1301AEUP+T implements a fully differential SAR architecture with integrated track-and-hold, supporting both unipolar and bipolar configurations across seven single-ended and three differential input voltage ranges. Its analog front-end includes ±16.5V fault protection on all channels and constant 17kΩ input resistance regardless of input voltage.
It uses four independent power domains-AVDD1/AGND1 (analog core), AVDD2/AGND2 (preamplifier), DVDD/DGND (digital logic), and DVDDO/DGNDO (I/O)-each requiring dedicated 0.1µF bypassing to minimize noise coupling. Reference operation is selectable via REFCAP voltage threshold between internal 4.096V bandgap and external 3.800V–4.136V sources.

Equivalent & Alternatives

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8684IPWR | 4-channel, 16-bit, 1MSPS, internal 4.096V ref, but only 4 single-ended inputs; no differential mode; requires external VREF for >±10V ranges | Higher speed but lacks true differential input capability and ±16.5V fault tolerance | Prefer MAX1301AEUP+T when differential sensing or field-wiring robustness is required |

FAQ
What is the maximum sample rate of the MAX1301AEUP+T?
The MAX1301AEUP+T achieves a maximum throughput rate of 115ksps in external clock mode with a 3.5MHz SCLK. This rate is maintained across all supported input ranges and configurations, including true-differential acquisitions. The device also supports internal clock mode (106ksps) and external acquisition mode (84ksps), each with distinct timing trade-offs for system synchronization.
Does the MAX1301AEUP+T support true differential input operation?
Yes, the MAX1301AEUP+T supports true differential input operation across two independent channels (CH0–CH1 and CH2–CH3). Each differential pair accepts input spans of (±3 × VREF)/2, ±3 × VREF, or ±6 × VREF - delivering up to ±24.576V full-scale range with the internal 4.096V reference. Common-mode voltage range is -14V to +9V, and CMRR exceeds 75dB at (±3 × VREF)/4 range.
How does the MAX1301AEUP+T handle overvoltage conditions on its analog inputs?
The MAX1301AEUP+T features ±16.5V overvoltage tolerance on all analog input pins (CH0–CH3), implemented via back-to-back diode clamping to AGND1 and AVDD1. A fault on any idle channel does not affect conversions on active channels. This protection operates continuously without external components, enabling direct connection to industrial field wiring prone to transients and miswiring.
Can the MAX1301AEUP+T operate with an external reference voltage?
Yes, the MAX1301AEUP+T accepts an external reference voltage between 3.800V and 4.136V applied to the REF pin. Reference mode is selected automatically based on the REFCAP node voltage: if REFCAP > VAVDD1 − 0.1V, external reference mode activates; if REFCAP < VAVDD1 − 0.4V, internal 4.096V reference mode engages. Bypass REF with 1.0µF to AGND1 for stability.
What power supply domains does the MAX1301AEUP+T require?
The MAX1301AEUP+T requires four independent supply domains: AVDD1/AGND1 (+4.75V to +5.25V, ~3mA) for SAR core, AVDD2/AGND2 (+4.75V to +5.25V, ~13.5mA) for preamplifier, DVDD/DGND (+4.75V to +5.25V, ~0.8mA) for digital logic, and DVDDO/DGNDO (+2.7V to +5.25V, ~0.01–1mA) for I/O interface. Each domain must be bypassed to its respective ground with 0.1µF ceramic capacitors.
