Product details
Overview
MAX1030BCEG+T from Maxim Integrated is a 10-bit, 300ksps serial analog-to-digital converter with integrated temperature sensor (±0.7°C accuracy at +25°C), 16-entry FIFO, and internal 4.096V reference. It supports 16 single-ended or 8 true differential input channels in unipolar/bipolar modes, operates from a single +5V supply, and interfaces via 10MHz SPI/QSPI/MICROWIRE-compatible 3-wire serial port. It is used in industrial control systems for multichannel voltage and temperature monitoring.
For engineers reviewing the MAX1030BCEG+T datasheet, MAX1030BCEG+T pinout, MAX1030BCEG+T application, or MAX1030BCEG+T equivalent, this page delivers verified technical context, exact pin functions, real-world use scenarios, and two validated alternative parts - all grounded in the official MAX1030 datasheet Rev 4 (2011) and Maxim's product documentation.
Technical Context
The MAX1030BCEG+T implements a fully differential successive-approximation register (SAR) ADC architecture with on-chip track-and-hold, supporting both single-ended and true differential acquisition. Its internal oscillator enables autonomous conversion timing in clock modes 00/01/10, while mode 11 supports externally clocked operation up to 300ksps.
It integrates a dedicated temperature-sensing path using the same SAR core, with results delivered in two's complement format at 1/8°C resolution. The 16-deep FIFO buffers conversion results and temperature readings independently, enabling burst acquisition without serial bus contention.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit multichannel ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 8-bit resolution, 200ksps max, no internal temp sensor or FIFO; 8-channel single-ended only | Lacks temperature monitoring and burst acquisition capability - unsuitable for thermal-aware systems | Select only if lower resolution and simpler channel count suffice, and external reference is acceptable |
| AD7490BRUZ | 12-bit resolution, 1MSPS, 16-channel single-ended, no internal temp sensor; requires external reference | Higher precision and speed but no integrated thermal sensing - adds BOM cost and layout complexity | Prefer when absolute accuracy >10-bit and sampling >300ksps is required; verify external reference stability and layout |
Compared with ADS7822U and AD7490BRUZ, the MAX1030BCEG+T uniquely combines 10-bit precision, integrated temperature sensing, 16-channel flexibility, and autonomous FIFO buffering - making it optimal for compact, thermally aware embedded data acquisition where component count and firmware overhead must be minimized.

FAQ
What is the operating temperature range specified for the MAX1030BCEG+T?
The MAX1030BCEG+T is specified over the extended industrial temperature range of -40°C to +85°C. This rating applies to all key specifications including INL/DNL, reference voltage stability, temperature sensor accuracy, and supply current - ensuring reliable operation in demanding environments such as factory automation and outdoor instrumentation. The 'E' grade suffix in MAX1030BCEG+T explicitly denotes this extended range.
Does the MAX1030BCEG+T require an external reference voltage?
No, the MAX1030BCEG+T does not require an external reference voltage. It includes a factory-trimmed internal 4.096V reference with ±20ppm/°C temperature coefficient and 200μVRMS noise. An external differential reference can be used instead by connecting to REF+ and REF−, but the internal reference remains active for temperature measurements regardless of reference selection.
How many analog input channels does the MAX1030BCEG+T support in differential mode?
The MAX1030BCEG+T supports eight true differential input channels: AIN0/AIN1, AIN2/AIN3, AIN4/AIN5, AIN6/AIN7, AIN8/AIN9, AIN10/AIN11, AIN12/AIN13, and AIN14/AIN15. This full 16-input complement is exclusive to the MAX1030; the MAX1028 supports six differential pairs, and the MAX1026 supports four.
Can the MAX1030BCEG+T perform simultaneous sampling across multiple channels?
No, the MAX1030BCEG+T does not support simultaneous sampling. It uses a single SAR ADC core with a multiplexed analog input stage, performing sequential conversions across selected channels. However, its 300ksps maximum rate and 16-entry FIFO enable rapid scanning with minimal inter-channel timing skew - sufficient for most multiplexed data acquisition applications including motor control feedback and environmental monitoring.
What package type is used for the MAX1030BCEG+T, and is the exposed pad required?
The MAX1030BCEG+T uses a 28-pin 5mm × 5mm TQFN package with exposed pad (EP). The exposed pad is electrically connected to GND and must be soldered to a PCB thermal pad tied to the ground plane. This connection is mandatory for proper thermal dissipation, noise immunity, and compliance with the device's absolute maximum ratings - omitting it risks parametric shift and reliability degradation.
