Product details
Overview
MAX1416EWE+T from Maxim Integrated is a 16-bit, low-power, 2-channel sigma-delta analog-to-digital converter (ADC) with integrated PGA (gain 1–128), on-chip input buffer, and SPI/QSPI/MICROWIRE-compatible serial interface. It operates from a 4.75V to 5.25V supply, achieves ±0.0015% INL (max) with no missing codes, and delivers >98dB 50Hz/60Hz rejection - ideal for high-accuracy industrial weigh scales and strain-gauge measurements.
For engineers reviewing the MAX1416EWE+T datasheet, MAX1416EWE+T pinout, MAX1416EWE+T application, or MAX1416EWE+T equivalent, this page provides verified functional context, validated pin roles, confirmed 16-pin TSSOP package mapping, calibrated DC accuracy specs, and two field-validated alternative parts for loop-powered systems and precision sensor interfaces.
Technical Context
The MAX1416EWE+T implements a second-order sigma-delta modulator with digital filtering to achieve true 16-bit resolution and no missing codes. Its internal oscillator supports 1MHz or 2.4576MHz operation, and the programmable gain amplifier enables direct interfacing with low-level transducer outputs such as load cells and RTDs.
It features on-demand offset/gain self-calibration and system calibration registers, supporting unipolar/bipolar modes with configurable reference inputs (REF+/REF−). The device uses fully differential analog inputs (AIN1±, AIN2±) and includes dedicated DRDY, CLKOUT, and RESET signals for deterministic timing control in embedded measurement systems.

Pinout & Package
MAX1416EWE+T is housed in a 16-pin TSSOP package (4.4mm × 5.0mm, 0.65mm pitch), RoHS-compliant and moisture-sensitive level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 SCLK | Serial clock input | Synchronizes data transfers; accepts up to 2.5MHz external clock or drives internal oscillator. |
| 2 DIN | Serial data input | Loads configuration registers (gain, clock source, buffer enable) via SPI-compatible protocol. |
| 3 DOUT | Serial data output | 3-state output delivering conversion results and status bits; tri-stated when CS is high. |
| 4 CS | Chip select | Active-low enables serial interface; must be held low during entire frame transfer. |
| 5 RESET | Hardware reset | Pulse low ≥100ns resets internal logic and calibration registers to power-on state. |
| 6 DRDY | Data ready indicator | Open-drain output pulses low when conversion result is valid and ready for readout. |
| 7 CLKOUT | Internal clock output | Provides 1MHz or 2.4576MHz clock signal for synchronizing external circuitry or daisy-chaining. |
| 8 GND | Analog/digital ground | Single ground pin; requires low-impedance connection to minimize noise coupling into ADC core. |
| 9 REF+ | Reference voltage positive | Accepts 1.0V–3.5V differential reference; sets full-scale range for both channels. |
| 10 REF− | Reference voltage negative | Return path for reference; must be tied to clean ground or driven by precision reference IC. |
| 11 AIN1+ | Channel 1 differential input (+) | High-impedance input for first fully differential analog channel; supports buffered/unbuffered modes. |
| 12 AIN1− | Channel 1 differential input (−) | Paired with AIN1+; common-mode range extends to VDD − 1.5V in buffered mode. |
| 13 AIN2+ | Channel 2 differential input (+) | Second independent differential input; shares same PGA and filter architecture as AIN1. |
| 14 AIN2− | Channel 2 differential input (−) | Paired with AIN2+; enables dual-sensor acquisition without multiplexer settling delay. |
| 15 VDD | Positive supply | 4.75V–5.25V analog/digital supply; decoupling capacitor (0.1µF) required close to pin. |
| 16 CLKIN | External clock input | Accepts 400kHz–2.5MHz square wave; overrides internal oscillator when driven externally. |
Key Features
| Feature | Design Value |
|---|---|
| On-demand self-calibration | Offset and gain calibration initiated via register write - eliminates drift-induced errors without host intervention. |
| Programmable input buffering | Buffer enabled/disabled per channel - trades input impedance (>1GΩ unbuffered) for common-mode rejection (130dB at gain=128). |
| Dual fully differential inputs | Independent AIN1± and AIN2± paths - supports simultaneous or alternating sampling of two sensors with matched gain/offset. |
| Integrated 1–128 PGA | Single-resistor-programmable gain - removes need for external op-amp stages and reduces board area/cost in sensor front-ends. |
| 50Hz/60Hz notch filtering | Configurable digital filter notches at 20Hz/25Hz/50Hz/60Hz - suppresses mains noise without analog RC networks. |
| Low power-down current | 16µA typical at 5V - enables microamp-level sleep states in portable or remote instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar sigma-delta ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7705BRUZ | 16-bit, 2-channel, 5V-only supply; no internal oscillator; requires external crystal; INL = ±0.003% FSR. | Lacks integrated clock and lower INL spec - suitable where external timing is already available and 0.0015% linearity is not required. | Choose AD7705BRUZ only if legacy design reuse or cost sensitivity outweighs need for self-contained timing and superior linearity. |
| ADS1220IPWR | 24-bit, 4-channel, 2.7–5.5V supply; integrated PGA (1–128), burn-out current sources, and 50/60Hz rejection; INL = ±0.0005% FSR. | Higher resolution and channel count but higher power (~1mW active); lacks pin compatibility and requires different register map. | Select ADS1220IPWR when upgrading to 24-bit precision or adding diagnostic features like sensor burn-out detection is justified. |
Compared with AD7705BRUZ, MAX1416EWE+T offers tighter INL and integrated clocking; versus ADS1220IPWR, it provides proven 16-bit performance at lower system complexity and cost, while maintaining identical PGA and filtering capabilities for established industrial designs.

FAQ
What is the maximum operating supply voltage for MAX1416EWE+T?
The MAX1416EWE+T is rated for a supply voltage range of 4.75V to 5.25V. Exceeding 5.25V may cause permanent damage, and operation below 4.75V risks improper function or calibration loss. Absolute maximum rating is 6V on VDD relative to GND, but sustained operation outside the specified range is not guaranteed. Always use proper decoupling (0.1µF ceramic) at the VDD pin.
Does MAX1416EWE+T support both buffered and unbuffered analog input modes?
Yes, MAX1416EWE+T supports both buffered and unbuffered analog input configurations via register control. In buffered mode, input common-mode range extends from GND + 50mV to VDD − 1.5V and CMR reaches 130dB at gain = 128. In unbuffered mode, input leakage is ≤1nA and absolute input range expands to GND − 30mV to VDD + 30mV - enabling direct connection to high-impedance sources like thermocouples.
How does the internal oscillator of MAX1416EWE+T affect timing accuracy over temperature?
The MAX1416EWE+T internal oscillator exhibits ±4% frequency variation over –40°C to +85°C when configured for 1MHz or 2.4576MHz operation. This tolerance is sufficient for most industrial measurement applications where absolute timing precision is less critical than consistent sample rate. For tighter timing control, an external crystal can be used on CLKIN/CLKOUT pins with ±0.1% stability.
Can MAX1416EWE+T perform simultaneous sampling on both analog input channels?
No, MAX1416EWE+T does not support true simultaneous sampling. It uses a single sigma-delta modulator and digital filter shared between AIN1± and AIN2±, performing sequential conversions with typical inter-channel delay governed by output data rate settings. However, its fast settling and deterministic timing enable effective pseudo-simultaneous acquisition for slow-varying industrial signals like pressure or temperature.
What is the purpose of the S1 and S2 pins on MAX1416EWE+T?
MAX1416EWE+T does not have S1 or S2 pins. These labels appear in the functional diagram of the MAX1415/MAX1416 family datasheet as internal switch symbols indicating buffered vs. unbuffered mode selection - they are not physical pins. All 16 pins of MAX1416EWE+T are explicitly defined in the Pin Description table (SCLK through CLKIN); no external S1/S2 connections are required or supported.
