Analog Devices Inc./Maxim Integrated MAX11602EEE+T

Overview

MAX11602EEE+T from Maxim Integrated is an 8-bit, 8-channel, low-power analog-to-digital converter with integrated track/hold, 4.096V internal reference, I²C-compatible 2-wire serial interface, and operation from a 4.5V–5.5V single supply. It delivers 188ksps throughput with 350µA supply current and ±1 LSB total unadjusted error, targeting compact, battery-sensitive systems such as portable medical monitors and solar-powered remote sensors.

For engineers reviewing the MAX11602EEE+T datasheet, MAX11602EEE+T pinout, MAX11602EEE+T application, or MAX11602EEE+T equivalent, key selection criteria include its 16-pin QSOP package, software-configurable unipolar/bipolar and single-ended/pseudo-differential input modes, internal FIFO with channel-scan capability, and guaranteed operation across –40°C to +85°C.

Technical Context

The MAX11602EEE+T employs successive-approximation architecture with on-chip track/hold capacitor (CT/H) and switched-capacitor DAC. Conversion requires eight clock cycles per sample, with acquisition time dependent on source impedance and clock mode-2 internal clock cycles in internal-clock mode, or one SCL period in external-clock mode.

Its analog input multiplexer supports eight single-ended or four pseudo-differential channels, with configurable reference selection (internal 4.096V or external 1V–VDD). The device uses I²C Fast Mode (400kHz) and High-Speed Mode (1.7MHz), with SDA/SCL pins implementing open-drain logic and requiring external pull-ups.

Key Specifications

Pinout & Package

MAX11602EEE+T is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.154" body width and 0.025" lead pitch, optimized for high-density PCB layouts while maintaining hand-solderability.

MAX11602EEE+T is available at Aetrix Electronics and suitable for portable medical sensors, battery-powered test equipment, and solar-powered remote systems requiring stable component supply, long-term lifecycle assurance, and RoHS-compliant packaging.

Supply support for MAX11602EEE+T includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Maxim Integrated (now part of Analog Devices) designs precision analog, mixed-signal, and power-management ICs for demanding industrial, medical, and communications applications.

The MAX11600–MAX11605 family was engineered for ultra-low-power, space-constrained systems requiring multichannel data acquisition without external support components - emphasizing integration, supply flexibility, and ease of I²C-based firmware integration.

FAQ

What is the internal reference voltage of MAX11602EEE+T?

The MAX11602EEE+T features a factory-trimmed 4.096V internal reference, specified from 3.850V to 4.342V over temperature. This reference can be used directly as the ADC's full-scale reference or overridden by an external voltage applied to the REF pin within the 1V to VDD range. Its 120ppm/°C temperature coefficient ensures stability across –40°C to +85°C operation.

Does MAX11602EEE+T support pseudo-differential input mode?

Yes, MAX11602EEE+T supports pseudo-differential input mode via the SGL/DIF bit in its configuration byte. In this mode, it converts the difference between a selected positive input (e.g., AIN0) and a fixed negative input (GND or AINx depending on setup), with the negative input required to remain stable within ±0.5 LSB. This enables rejection of common-mode noise while retaining single-ended signal routing simplicity.

What supply voltage range is valid for MAX11602EEE+T?

MAX11602EEE+T operates exclusively from a 4.5V to 5.5V single supply, as confirmed by its ordering information and electrical characteristics tables. It is not rated for 2.7–3.6V operation - that range applies only to the MAX11601/MAX11603/MAX11605 variants with 2.048V reference. Using voltages outside 4.5–5.5V may cause functional failure or reliability degradation.

How many analog input channels does MAX11602EEE+T have?

MAX11602EEE+T provides 8 analog input channels (AIN0–AIN7), configurable as eight single-ended inputs or four pseudo-differential pairs. This is explicitly defined in the Ordering Information table and General Description section, distinguishing it from the 4-channel (MAX11600/MAX11601) and 12-channel (MAX11604/MAX11605) members of the same family.

Is MAX11602EEE+T pin-compatible with MAX11603EEE+?

Yes, MAX11602EEE+T and MAX11603EEE+ share identical 16-pin QSOP packaging and pinout - including identical assignments for AIN0–AIN7, SCL, SDA, GND, VDD, and REF. The sole functional difference is the internal reference voltage (4.096V vs. 2.048V), making them drop-in replacements where reference voltage requirements align with system signal range.
