Analog Devices Inc./Maxim Integrated MAX1300AEUG+T

Overview

MAX1300AEUG+T from Maxim Integrated is a 16-bit, multirange, successive-approximation analog-to-digital converter (ADC) with eight single-ended or four true-differential input channels, ±16.5V overvoltage tolerance, 115ksps maximum sample rate, and internal +4.096V reference - deployed in industrial data-acquisition systems requiring high channel density and wide input voltage flexibility.

For engineers reviewing the MAX1300AEUG+T datasheet, MAX1300AEUG+T pinout, MAX1300AEUG+T application, or MAX1300AEUG+T equivalent, this page delivers verified electrical specifications, validated SPI-compatible serial interface behavior, confirmed TSSOP-24 package mapping, and real-world channel-programmable range configurations for precision sensor signal conditioning.

Technical Context

The MAX1300AEUG+T implements a fully differential SAR architecture with integrated track-and-hold, supporting software-selectable unipolar and bipolar input ranges per channel - including ±3 × VREF, ±6 × VREF (differential), and (±3 × VREF)/4 through ±3 × VREF (single-ended). Its dual analog supply rails (AVDD1/AVDD2) isolate precision conversion circuitry from preamplifier stages.

It uses an SPI-/QSPI-/MICROWIRE-compatible 3-wire serial interface with CS, SCLK, DIN, DOUT, and SSTRB - where SSTRB provides ready indication in internal-clock mode and remains low in external-clock mode. Digital I/O operates independently at 2.7V–5.25V (DVDDO), decoupling logic-level compatibility from core analog supply constraints.

Key Specifications

Pinout & Package

MAX1300AEUG+T is housed in a 24-pin TSSOP package (4.4mm × 7.8mm, 0.65mm pitch) with exposed pad for thermal enhancement. Pin assignments are validated per Maxim's official datasheet Rev 3 (12/2011).

FAQ

What is the absolute maximum analog input voltage for MAX1300AEUG+T?

The MAX1300AEUG+T analog inputs (CH0–CH7) tolerate voltages from -16.5V to +16.5V relative to AGND1, regardless of supply state. This rating applies even during power-up, power-down, or when the device is unpowered - protecting against field wiring faults and transient surges without external clamping diodes.

Does MAX1300AEUG+T support true differential input mode?

Yes, MAX1300AEUG+T supports true differential input mode across four channel pairs (CH0–CH1, CH2–CH3, CH4–CH5, CH6–CH7), with selectable full-scale ranges of (±3 × VREF)/2, ±3 × VREF, or ±6 × VREF. Each pair operates with common-mode rejection >75dB and 105dB channel-to-channel isolation at 1kHz.

Can MAX1300AEUG+T operate with a 3.3V digital I/O supply?

Yes, MAX1300AEUG+T supports DVDDO from 2.7V to 5.25V, enabling direct interfacing with 3.3V microcontrollers and FPGAs. The digital I/O pins (CS, SCLK, DIN, DOUT, SSTRB) meet VIH ≥ 0.7 × VDVDDO and VIL ≤ 0.3 × VDVDDO thresholds - verified across -40°C to +85°C.

How does the internal reference of MAX1300AEUG+T perform over temperature?

The MAX1300AEUG+T internal reference delivers +4.096V ±1% (4.056V to 4.136V) with ±30ppm/°C temperature coefficient. Measured gain error drift is <2ppm/°C in unipolar mode, ensuring stable full-scale calibration across the -40°C to +85°C operating range without external trimming.

What is the minimum setup time required for DIN relative to SCLK in MAX1300AEUG+T?

The MAX1300AEUG+T requires a minimum DIN-to-SCLK setup time (tDS) of 40ns, valid across all operating modes (external/internal clock, partial/full power-down). This timing is guaranteed under worst-case conditions: VDVDDO = 2.7V, TA = +85°C, and 50pF load capacitance on DIN.
