Product details
Overview
MAX1060AEEI+ from Maxim Integrated is a 10-bit successive-approximation analog-to-digital converter (ADC) with 8-channel single-ended or 4-channel pseudo-differential input, internal +2.5V reference, byte-wide parallel (8+2) interface, and operation from a single +5V analog supply with user-adjustable digital logic level (+2.7V to +5.5V). It delivers 400ksps sampling rate, ±0.5 LSB INL, and 2.5mA supply current at full speed, targeting battery-powered data acquisition and industrial sensor interfacing.
For engineers reviewing the MAX1060AEEI+ datasheet, MAX1060AEEI+ pinout, MAX1060AEEI+ application, or MAX1060AEEI+ equivalent, key selection criteria include its software-configurable unipolar/bipolar input mode, fast 2µs wake-up from shutdown, internal track-and-hold with 6MHz full-power bandwidth, and QSOP-28 package compatibility with industrial temperature range (–40°C to +85°C).
Technical Context
The MAX1060AEEI+ implements a charge-redistribution SAR architecture with integrated track-and-hold, supporting both internal and external clock modes (7.6MHz max) and internal/external acquisition control via configurable control byte. Its analog front-end allows dynamic reconfiguration between single-ended (CH0–CH7) and pseudo-differential (CH0/CH1, CH2/CH3, etc.) input pairs, with COM referenced zero-code voltage.
Digital interface uses active-low CS, WR, RD, and INT signals with HBEN-controlled 10-bit data multiplexing (D0/D8 and D1/D9), enabling direct connection to 8-bit microprocessors. Power management includes two software-selectable power-down modes reducing supply current to <2µA in shutdown, while maintaining fast wake-up and stable reference performance across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - supports precise digitization of sensor outputs and control loop feedback signals within ±0.5 LSB INL error band. |
| Sampling Rate | 400ksps maximum - enables real-time capture of transients up to 350kHz full-linear bandwidth without aliasing when paired with anti-alias filtering. |
| Analog Input Configuration | 8-channel single-ended or 4-channel pseudo-differential - provides flexible signal routing for multi-sensor systems without external MUX hardware. |
| Reference | +2.5V internal bandgap reference (±20ppm/°C TC, ±100mV adjust range) - eliminates need for external reference IC in space-constrained designs. |
| Supply Current | 2.5mA at 400ksps, 400µA at 10ksps, 2µA in shutdown - enables ultra-low-power operation in duty-cycled measurement systems. |
| Digital Interface | Byte-wide parallel (D0–D7) + D8/D9 multiplexed via HBEN - simplifies µP interfacing with standard 8-bit data buses and avoids serial protocol overhead. |
| Operating Temperature | –40°C to +85°C - qualified for deployment in industrial control cabinets, energy meters, and medical monitoring equipment. |
Pinout & Package
MAX1060AEEI+ is housed in a 28-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch), optimized for high-density PCB layouts and automated assembly. Pin functions are validated per Maxim's official pin description table and functional diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 HBEN | High-byte enable control | Selects whether D0/D8 and D1/D9 carry MSBs (HBEN=1) or LSBs (HBEN=0); enables 10-bit readout over 8-bit bus. |
| 10 INT | Interrupt output | Active-low signal indicates conversion completion and data validity; synchronizes µP read timing without polling. |
| 11 RD | Read strobe input | Falling edge latches conversion result onto D0–D7 bus when CS is low; supports non-intrusive status checking. |
| 12 WR | Write strobe input | Rising edge loads control byte (channel select, unipolar/bipolar, acquisition mode) and initiates conversion sequence. |
| 13 CLK | Clock input | Accepts external 100kHz–7.6MHz TTL/CMOS clock or connects to VDD/GND for internal clock mode. |
| 14 CS | Chip select | Active-low enables digital interface; places D0–D7 in high-impedance state when deasserted to prevent bus contention. |
| 15–22 CH0–CH7 | Analog input channels | Eight single-ended inputs or four differential pairs; each protected by internal clamping diodes (GND−0.3V to VDD+0.3V). |
| 23 COM | Analog common reference | Sets zero-code voltage in single-ended mode; must remain stable to ±0.5 LSB during conversion. |
| 25 REFADJ | Reference buffer control | Connect to VDD to disable internal reference when using external REF source; bypass with 0.01µF capacitor. |
| 26 REF | Reference I/O | Outputs +2.5V internal reference or accepts external reference; requires 4.7µF capacitor to GND for stability. |
| 27 VDD | Analog supply | +5V ±10% analog power rail; bypass with 0.1µF capacitor to GND near pin for noise suppression. |
| 28 VLOGIC | Digital supply | +2.7V to +5.5V logic-level supply; decouples digital I/O voltage from analog domain for mixed-signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Software-configurable input topology | Runtime selection of unipolar/bipolar and single-ended/pseudo-differential modes via control byte - eliminates hardware redesign for varying sensor signal types. |
| Internal +2.5V reference with trim capability | ±20ppm/°C tempco and ±100mV REFADJ adjustment range - ensures stable accuracy across industrial temperature range without external components. |
| Low-power shutdown with fast wake-up | 2µA shutdown current and 2µs wake-up time - enables microsecond-scale duty cycling for ultra-low average power in portable instrumentation. |
| Integrated track-and-hold with 6MHz bandwidth | Eliminates need for external T/H amplifier; supports undersampling of high-frequency signals beyond Nyquist limit with proper anti-alias filtering. |
| Parallel (8+2) interface with HBEN multiplexing | Enables 10-bit data transfer using standard 8-bit µP data bus - reduces PCB trace count and simplifies firmware driver development. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit parallel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX1061AEEI+ | +3V analog supply (vs. +5V), identical pinout and feature set except lower supply voltage and reduced full-power bandwidth (3MHz vs. 6MHz). | Better suited for low-voltage embedded systems where +5V rail is unavailable; not drop-in compatible due to VDD voltage requirement mismatch. | Select MAX1061AEEI+ only when system-level power architecture mandates +3V analog operation and 3MHz bandwidth suffices. |
| ADS7822U | 8-bit resolution, SPI interface, +2.7V to +5.25V supply, no internal reference - requires external REF and serial interface logic. | Targets cost-sensitive, lower-precision applications with existing SPI infrastructure; lacks parallel bus simplicity and on-chip reference of MAX1060AEEI+. | Choose ADS7822U when board space permits serial interface and 8-bit resolution meets accuracy requirements, avoiding parallel bus routing complexity. |

FAQ
What is the operating temperature range of the MAX1060AEEI+?
The MAX1060AEEI+ is rated for operation from –40°C to +85°C, as confirmed by its "AEEI" suffix ordering code and electrical specifications tables covering that full industrial temperature range. This makes the MAX1060AEEI+ suitable for deployment in harsh environments such as factory automation controllers, outdoor energy meters, and portable medical devices without thermal derating.
Does the MAX1060AEEI+ require an external reference voltage?
No, the MAX1060AEEI+ includes a precision +2.5V internal bandgap reference with ±20ppm/°C temperature coefficient and ±100mV adjustment range via REFADJ. An external reference is optional and only needed when higher initial accuracy or different reference voltage is required; the internal reference eliminates BOM cost and board space for most applications.
How does the HBEN pin function in the MAX1060AEEI+?
The HBEN (High Byte Enable) pin on the MAX1060AEEI+ controls multiplexing of the 10-bit conversion result onto the 8-bit data bus: when HBEN = 1, D0/D8 and D1/D9 carry the two most significant bits (MSBs); when HBEN = 0, they carry the two least significant bits (LSBs). This allows full 10-bit readout using standard 8-bit microprocessor buses without additional latches or glue logic.
Can the MAX1060AEEI+ operate with a 3.3V digital supply?
Yes, the MAX1060AEEI+ supports digital logic supply voltages from +2.7V to +5.5V on the VLOGIC pin, fully compatible with 3.3V systems. The digital I/O levels (VIH/VIL, VOH/VOL) are specified down to VLOGIC = 2.7V, ensuring robust interfacing with 3.3V µPs and FPGAs while maintaining separate +5V analog supply (VDD) for optimal SNR performance.
What power-down modes are available on the MAX1060AEEI+?
The MAX1060AEEI+ offers two software-selectable power-down modes controlled by PD0/PD1 bits in the configuration byte: standby mode (reducing IDD to ~10µA) and full power-down mode (reducing IDD to 2µA). Both retain register settings and allow wake-up in 2µs via WR or CS assertion, enabling aggressive power cycling in battery-operated data loggers without losing configuration state.
