Product details
Overview
The MAX11059ECB+T from Maxim Integrated is an 8-channel, 14-bit simultaneous-sampling analog-to-digital converter with independent track-and-hold per channel, 250ksps throughput per channel, 0–5V input range, and internal 4.096V reference. It operates from 4.75V–5.25V analog and 2.7V–5.25V digital supplies, and targets high-precision multiphase motor control and power-grid protection systems.
For engineers reviewing the MAX11059ECB+T datasheet, MAX11059ECB+T pinout, MAX11059ECB+T application, or MAX11059ECB+T equivalent, this page delivers verified specifications, package mapping, functional pin definitions, real-world use cases, and validated alternative options for industrial measurement and control design.
Technical Context
This ADC employs parallel SAR architecture with eight independent T/H circuits enabling true simultaneous sampling across all channels. Its 20MHz bidirectional parallel interface supports direct host CPU connection without level shifting, while aperture delay (10ns) and channel-to-channel T/H matching (100ps) ensure precise phase-coherent acquisition for multi-sensor systems.
The device integrates a low-drift 4.096V internal reference (±4ppm/°C), accepts external references from 3.0V to 4.25V, and features ±20mA input clamps with external resistor overrange protection. Analog and digital supplies are fully decoupled, supporting mixed-voltage system interfacing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar simultaneous-sampling ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8588SIPM | 8-channel, 16-bit, SPI interface, 200ksps, external reference only, AVDD/DVDD = 5V only | Requires external reference and level-shifting for 3.3V hosts; lower throughput but higher resolution | Choose when 16-bit resolution is mandatory and SPI interface is preferred over parallel bus. |
| AD7606C-16BSTZ | 8-channel, 16-bit, parallel/SPI, 1MSPS aggregate, internal reference, AVDD = 5V, DVDD = 2.3–5.25V | Higher aggregate throughput (1MSPS) but shared T/H; not truly simultaneous across all 8 channels | Choose when higher speed is prioritized over strict channel-to-channel phase coherence. |
Compared with ADS8588SIPM and AD7606C-16BSTZ, the MAX11059ECB+T uniquely combines true 8-channel simultaneity, 14-bit performance with 84.5dB SNR, flexible dual-supply operation, and integrated reference-making it optimal for phase-critical industrial monitoring where timing integrity outweighs raw bit depth or aggregate rate.

FAQ
What is the maximum sampling rate per channel for the MAX11059ECB+T?
The MAX11059ECB+T achieves 250ksps per channel with true simultaneous sampling across all eight inputs. This rate is guaranteed over the full -40°C to +85°C operating temperature range and supports 100kHz Nyquist bandwidth for high-fidelity waveform capture in applications like motor current analysis and grid harmonic monitoring.
Does the MAX11059ECB+T require an external reference voltage?
No-the MAX11059ECB+T includes a low-drift 4.096V internal reference (±4ppm/°C) that supports its 0–5V input range. REFIO can also accept an external reference from 3.0V to 4.25V if system-level calibration or tighter tolerance is required, but external reference is optional, not mandatory.
What package type and pin count does the MAX11059ECB+T use?
The MAX11059ECB+T uses a 64-pin TQFP-EP (thin quad flat pack with exposed pad) measuring 10mm × 10mm. The exposed pad is internally connected to AGND and must be soldered to a large PCB ground plane for optimal thermal performance and analog noise suppression.
How does the MAX11059ECB+T handle overvoltage conditions on analog inputs?
The MAX11059ECB+T incorporates ±20mA internal input clamps on each CH0–CH7 pin. When paired with a single external series resistor per channel, these clamps provide robust overrange protection against transients up to ±7.5V relative to AGND, eliminating need for discrete TVS diodes in many industrial designs.
Can the MAX11059ECB+T interface directly with a 3.3V microcontroller?
Yes-the MAX11059ECB+T supports DVDD from 2.7V to 5.25V, allowing direct connection to 3.3V logic without level shifters. Its parallel interface (DB0–DB15, RD, WR, CS, CONVST) meets 3.3V-compatible voltage thresholds (VIH = 2.0V min, VIL = 0.8V max), and output drive strength (VOH = DVDD – 0.4V, VOL = 0.4V) ensures reliable signaling.
