Product details

Overview

MAX1092ACEG+T from Maxim Integrated is a 10-bit successive-approximation ADC with integrated +2.5V reference, 4-channel single-ended / 2-channel pseudo-differential analog input multiplexer, byte-wide parallel (8+2) interface, and software-configurable unipolar/bipolar operation. It operates from a single +5V analog supply and supports digital logic levels from +2.7V to +5.5V via VLOGIC, enabling direct interfacing with mixed-voltage microprocessors in portable data-acquisition systems.

For engineers reviewing the MAX1092ACEG+T datasheet, MAX1092ACEG+T pinout, MAX1092ACEG+T application, or MAX1092ACEG+T equivalent, key selection considerations include its 400ksps sampling rate, ±0.5 LSB INL, internal track-and-hold with 6MHz full-power bandwidth, low-power shutdown mode (<2µA), and 24-pin QSOP package compatibility with space-constrained industrial sensor nodes and battery-powered medical monitors.

Technical Context

The MAX1092ACEG+T implements a charge-redistribution SAR architecture with an internal 10-bit capacitive DAC and programmable input multiplexer. Its track-and-hold stage supports both internal and external acquisition modes, with aperture jitter as low as 50ps in external acquisition mode and conversion time fixed at 13 clock cycles.

It features dual-clock configuration (internal or external up to 7.6MHz), software-selectable power-down modes (standby and full shutdown), and configurable analog input topology-single-ended (CH0–CH3) or pseudo-differential (CH0/CH1, CH2/CH3)-with COM referenced zero-code alignment and ±0.5 LSB stability requirement during conversion.

Key Specifications

Parameter	Value and Actual Design Meaning
Resolution	10-bit SAR ADC with no missing codes over temperature - ensures monotonicity in closed-loop control feedback paths.
Sampling Rate	Up to 400ksps - supports real-time monitoring of fast transients in energy metering and motor current sensing.
INL / DNL	±0.5 LSB INL, ±1 LSB DNL - enables accurate DC measurement in patient monitoring ECG front-ends without calibration.
Reference	+2.5V internal bandgap reference (±20ppm/°C TC, ±100mV adjust range) - eliminates need for external precision reference in cost-sensitive designs.
Power Consumption	2.5mA at 400ksps, 400µA at 10ksps, <2µA in shutdown - extends battery life in handheld diagnostic tools.
Analog Input Range	Unipolar: 0 to +2.5V; Bipolar: –1.25V to +1.25V - accommodates both sensor output scaling and differential signal conditioning.
Interface	Byte-wide parallel (D0–D7) plus D8/D9 multiplexed via HBEN, with active-low CS/WR/RD/INT - simplifies glueless connection to 8051, ARM7, and FPGA host controllers.

Pinout & Package

MAX1092ACEG+T is housed in a 24-pin QSOP package (5.3mm × 7.6mm, 0.635mm pitch), optimized for high-density PCB layouts in portable instrumentation.

Pin/Terminal	Circuit Role	Design Meaning
1 HBEN	High-byte enable control	Selects whether D0–D7 carry LSBs (HBEN=0) or D8/D9 (HBEN=1); enables 10-bit read in two cycles without bus expansion.
10 INT	Interrupt output	Active-low open-drain flag signaling conversion completion and data readiness - synchronizes µP read timing without polling overhead.
11 RD	Active-low read strobe	When CS low, falling edge latches valid data onto D0–D7 - provides deterministic data capture aligned to system clock domain.
12 WR	Active-low write strobe	Initiates configuration write or acquisition start; rising edge triggers internal state machine - supports both internal and external acquisition sequencing.
13 CLK	Clock input/control	Accepts external 100kHz–7.6MHz clock or connects to VDD/GND to enable internal oscillator - decouples timing control from host processor.
14 CS	Active-low chip select	Tri-states all digital outputs (D0–D9, INT) when high - allows shared data bus operation with multiple peripherals.
22–19 CH0–CH3	Analog input channels	Four single-ended inputs (or two pseudo-differential pairs); each protected by internal clamps (GND−300mV to VDD+300mV).
23 COM	Common-mode reference	Sets zero-code voltage in single-ended mode; must remain stable within ±0.5 LSB during conversion - requires low-noise local ground routing.
24 GND	Analog/digital ground	Single ground pin shared by analog and digital sections - mandates star grounding and separate AGND/DGND plane stitching under pin.
26 REF	Reference buffer output	Provides regulated +2.5V output; requires 4.7µF bypass capacitor to GND - defines full-scale range and directly impacts gain accuracy.
27 VDD	+5V analog supply	Powers analog core and T/H stage; requires 0.1µF ceramic bypass close to pin - noise on VDD degrades SINAD below 60dB.
28 VLOGIC	+2.7V to +5.5V digital supply	Independently powers digital I/O drivers - enables interoperability with 3.3V or 5V µPs without level shifters.

Key Features

Feature	Design Value
Software-configurable input topology	Runtime selection between 4-channel single-ended or 2-channel pseudo-differential mode via control byte - adapts to varying sensor types without hardware change.
Internal track-and-hold with 6MHz bandwidth	Supports undersampling of signals beyond Nyquist (e.g., 175kHz sine at 400ksps) - enables RF front-end digitization in spectrum analyzers.
Two-stage power-down control	Standby mode (1.0mA) and full shutdown (<2µA) reduce quiescent current by >99% between conversions - critical for duty-cycled IoT sensor nodes.
Programmable unipolar/bipolar operation	Single control bit selects input range (0–2.5V or ±1.25V) - simplifies signal conditioning for AC-coupled transducers and DC-coupled thermocouples.
On-chip +2.5V reference with trim capability	REFADJ pin allows ±100mV adjustment of internal reference - compensates for board-level voltage drop and improves absolute accuracy to ±0.5%.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 10-bit parallel-output ADC applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MAX1093ACEG+	+3V analog supply (VDD = 2.7V to 3.6V), same 24-pin QSOP footprint and pinout - lower power but reduced dynamic range (SINAD = 58dB vs. 60dB).	Preferred for ultra-low-power battery systems where 3.3V rail is standard and 2.5V reference tolerance is acceptable.	Select MAX1093ACEG+ only if system uses 3.3V analog supply and can tolerate 2dB lower SNR in high-frequency signal capture.
ADS7822U	8-bit resolution, SPI interface, 200ksps max rate, no internal reference - requires external REF and level-shifting for 5V µP interfacing.	Suitable for cost-sensitive, non-critical measurements where 8-bit resolution suffices and serial interface reduces PCB routing complexity.	Choose ADS7822U only when design prioritizes minimal pin count over resolution and can accommodate external reference sourcing and SPI firmware overhead.

Compared with MAX1093ACEG+, the MAX1092ACEG+ delivers higher full-scale range and better noise performance at +5V operation; versus ADS7822U, it offers 4× resolution, parallel throughput, and integrated reference - making it optimal for precision, speed-critical, and space-constrained embedded data acquisition.

FAQ

What is the maximum sampling rate supported by the MAX1092ACEG+T?

The MAX1092ACEG+T supports a maximum sampling rate of 400ksps when driven by a 7.6MHz external clock or configured for internal clock mode. At this rate, total conversion time is 13 clock cycles (≈1.7µs), and power consumption is 2.5mA. Lower rates (e.g., 10ksps) reduce current to 400µA, enabling adaptive power scaling in battery-operated devices.

Does the MAX1092ACEG+T require an external reference voltage?

No, the MAX1092ACEG+T includes a precision +2.5V internal bandgap reference with ±20ppm/°C temperature coefficient and ±100mV trim range via REFADJ. An external reference may be used by connecting REFADJ to VDD and applying a stable voltage to the REF pin, but it is not required - the internal reference meets ±0.5% initial accuracy and supports uncalibrated operation in most industrial applications.

How many analog input channels does the MAX1092ACEG+T support in single-ended mode?

The MAX1092ACEG+T supports four single-ended analog input channels (CH0–CH3) in single-ended mode. In pseudo-differential mode, it supports two differential pairs (CH0/CH1 and CH2/CH3). This is distinct from the pin-compatible MAX1090, which offers eight single-ended or four pseudo-differential channels in the same functional architecture.

Can the MAX1092ACEG+T interface directly with a 3.3V microcontroller?

Yes, the MAX1092ACEG+T supports direct interfacing with 3.3V microcontrollers via its VLOGIC pin, which accepts +2.7V to +5.5V digital supply voltage. When VLOGIC = 3.3V, all digital outputs (D0–D9, INT) are 3.3V-compatible, and input thresholds (VIH/VIL) are scaled accordingly - eliminating the need for external level translators in mixed-voltage systems.

What is the purpose of the HBEN pin on the MAX1092ACEG+T?

The HBEN (High-Byte Enable) pin on the MAX1092ACEG+T controls multiplexing of the 10-bit conversion result across the 8-bit data bus: when HBEN = 0, D0–D7 carry the 8 LSBs; when HBEN = 1, D0/D8 and D1/D9 carry the two MSBs. This allows full 10-bit resolution to be read in two consecutive 8-bit cycles without requiring a wider data bus or additional address lines.
