Product details
Overview
MAX1092BCEG+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. Designed for portable data-acquisition systems requiring low power and compact size.
For engineers reviewing the MAX1092BCEG+T datasheet, MAX1092BCEG+T pinout, MAX1092BCEG+T application, or MAX1092BCEG+T equivalent, key selection criteria include its 400ksps sampling rate, ±0.5 LSB INL, 2.5mA active current at full speed, 2µs wake-up time, and 24-pin QSOP package compatibility with space-constrained industrial sensor interfaces and battery-powered patient monitors.
Technical Context
The MAX1092BCEG+T implements a charge-redistribution SAR architecture with an internal track-and-hold stage offering 6MHz full-power bandwidth and 350kHz full-linear bandwidth. Its control byte (D7–D0) configures acquisition mode (internal/external), clock source (internal/external), unipolar/bipolar range, and channel selection - enabling flexible timing and signal conditioning without external logic.
It features dual power-down modes: standby (≤10µA) and full shutdown (≤2µA), triggered by software control bits PD0/PD1. The on-chip +2.5V bandgap reference has ±2ppm/°C drift and supports external reference override via REFADJ tied to VDD, while VLOGIC decouples digital I/O voltage from analog supply for mixed-voltage system interfacing.
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 capture of audio-band signals and fast transients in energy metering. |
| INL / DNL | ±0.5 LSB integral nonlinearity, ±1 LSB differential nonlinearity - meets precision requirements for medical-grade patient monitoring. |
| Reference | +2.5V internal reference with ±20ppm/°C TC - eliminates need for external reference in cost-sensitive industrial data loggers. |
| Power Consumption | 2.5mA at 400ksps, 400µA at 10ksps, 2µA in shutdown - enables >1-year battery life in wireless sensor nodes. |
| Analog Inputs | 4 single-ended or 2 pseudo-differential channels - matches typical multi-sensor configurations in HVAC controllers. |
| Interface | Byte-wide parallel (D0–D7 + D8/D9 multiplexed via HBEN) with INT interrupt - simplifies connection to legacy 8-bit microcontrollers without FIFO or DMA overhead. |
Pinout & Package
MAX1092BCEG+T is housed in a 24-pin QSOP package (5.3mm × 7.8mm body, 0.635mm pitch), optimized for high-density PCB layouts in portable instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CH0–CH3 | Analog input channels | Four dedicated single-ended inputs; in pseudo-differential mode, paired as CH0/CH1 and CH2/CH3 - supports differential thermocouple or bridge sensor readout. |
| COM | Analog ground reference | Sets zero-code voltage in single-ended mode; must remain stable to ±0.5 LSB during conversion - requires local 0.1µF bypass to GND. |
| REF / REFADJ | Reference buffer output / bandgap adjust | REF outputs +2.5V; REFADJ disables internal reference when tied to VDD - enables seamless migration to higher-accuracy external references. |
| VDD / VLOGIC | Analog / digital supply rails | VDD = +5V ±10% analog supply; VLOGIC = +2.7V to +5.5V - allows direct interfacing with 3.3V or 5V µPs without level shifters. |
| CS / WR / RD / INT / HBEN | Parallel control and status signals | Standard 8080-style bus interface; HBEN selects MSB/LSB byte - reduces data bus width requirement in resource-limited embedded designs. |
| D0/D8–D7 | Bidirectional data bus | Three-state outputs driven by VLOGIC - prevents bus contention during multi-device sharing; compatible with TTL/CMOS logic families. |
Key Features
| Feature | Design Value |
|---|---|
| Software-configurable input mode | Single-ended (4 ch) or pseudo-differential (2 ch) + unipolar/bipolar selection via control byte - eliminates external multiplexer and polarity-reversal circuitry. |
| Internal track-and-hold | 6MHz full-power bandwidth with 3.2µs acquisition time - captures fast-rising pulses in motor current sensing without external sample-hold IC. |
| Two-tier power-down | Standby (≤10µA) and full shutdown (≤2µA) modes activated by PD0/PD1 bits - enables adaptive power management in duty-cycled IoT edge nodes. |
| Fast wake-up | 2µs transition from shutdown to valid conversion - supports burst-mode acquisition in event-triggered data logging. |
| On-chip +2.5V reference | ±0.5% initial accuracy, ±2ppm/°C drift, 4.7µF REF bypass - achieves <±1 LSB total error over 0°C to +70°C without calibration. |

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 |
|---|---|---|---|
| ADS7822U | 8-bit resolution, SPI interface, no internal reference - requires external 2.5V reference and level-shifting for 3.3V µPs. | Better suited for cost-sensitive, lower-precision motor control feedback where 10-bit resolution is unnecessary. | Select if system already uses SPI peripherals and 8-bit accuracy suffices; avoid if reference integration or parallel bus compatibility is required. |
| MAX11602EEE+ | 12-bit resolution, I²C interface, internal reference, 8-channel single-ended - lacks pseudo-differential mode and parallel bus. | Ideal for new designs using modern 3.3V microcontrollers with I²C peripherals and higher resolution needs. | Choose for upgrade paths requiring >10-bit precision and simplified two-wire interconnect; not drop-in due to interface and pinout mismatch. |
Compared with ADS7822U and MAX11602EEE+, the MAX1092BCEG+T uniquely combines 10-bit accuracy, integrated +2.5V reference, 4-channel flexibility, and byte-wide parallel interface in a 24-pin QSOP - making it optimal for retrofitting legacy 8-bit µP systems with minimal layout change.

FAQ
What is the maximum sampling rate of the MAX1092BCEG+T?
The MAX1092BCEG+T achieves a maximum sampling rate of 400ksps under standard conditions (VDD = VLOGIC = +5V, fCLK = 7.6MHz). This rate is maintained across its full operating temperature range (0°C to +70°C) and supports real-time digitization of signals up to 350kHz full-linear bandwidth. Conversion time is fixed at 13 clock cycles, yielding 3.2µs per sample at maximum clock frequency.
Does the MAX1092BCEG+T require an external reference voltage?
No, the MAX1092BCEG+T includes a precision +2.5V internal bandgap reference with ±0.5% initial accuracy and ±2ppm/°C temperature coefficient. An external reference can be used by connecting REFADJ to VDD and applying the reference to the REF pin, but it is not required. The internal reference eliminates BOM cost and board area in most portable and industrial applications.
How many analog input channels does the MAX1092BCEG+T support?
The MAX1092BCEG+T supports four single-ended analog input channels (CH0–CH3) or two pseudo-differential pairs (CH0/CH1 and CH2/CH3). This configuration is selected via the SGL/DIF bit in the control byte. Unlike the MAX1090, it does not support eight single-ended channels - the 24-pin QSOP package constrains routing to four dedicated inputs.
What power-saving modes are available on the MAX1092BCEG+T?
The MAX1092BCEG+T offers two software-selectable power-down modes controlled by PD0 and PD1 bits: standby mode (≤10µA supply current) and full shutdown mode (≤2µA). Both modes retain register settings and allow wake-up in 2µs. These modes are activated between conversions to reduce average power in battery-operated systems such as handheld test equipment and remote sensors.
Is the MAX1092BCEG+T compatible with 3.3V microcontrollers?
Yes, the MAX1092BCEG+T supports digital I/O voltage levels from +2.7V to +5.5V via the VLOGIC pin. When interfaced with a 3.3V microcontroller, VLOGIC is connected to +3.3V, ensuring correct logic thresholds (VIH = 2.0V min, VIL = 0.8V max) and output drive levels (VOH = VLOGIC − 0.5V, VOL = 0.4V max). No level-shifting circuitry is needed.
