Product details
Overview
MAX1063BEEG from Maxim Integrated is a 10-bit successive-approximation ADC with 4-channel single-ended / 2-channel pseudo-differential analog input multiplexing, +2.5V internal reference, byte-wide parallel (8+2) interface, and 250ksps sampling rate. It operates from a single +3V analog supply and supports digital logic levels from +1.8V to +3.6V via dedicated VLOGIC pin, enabling direct interfacing with low-voltage microprocessors in portable data-acquisition systems.
For engineers reviewing the MAX1063BEEG datasheet, MAX1063BEEG pinout, MAX1063BEEG application, or MAX1063BEEG equivalent, this page delivers verified electrical parameters, validated 24-pin QSOP package mapping, confirmed timing behavior under internal/external clock modes, and real-world use cases in patient monitoring and energy management where low power (1.9mA at 250ksps) and fast wake-up (2µs) are critical.
Technical Context
The MAX1063BEEG implements a charge-redistribution SAR architecture with integrated track/hold, supporting both internal (3MHz full-power bandwidth) and external clock operation. Its analog front-end allows software-configurable unipolar/bipolar and single-ended/pseudo-differential modes, with COM referenced zero-code alignment and ±0.5 LSB INL over temperature.
Conversion is initiated by a control byte written via the parallel interface, defining channel selection (CH0–CH3), acquisition mode (internal/external), and input configuration. The device features two software-selectable power-down modes-standby (10µA) and full shutdown (2µA)-and uses HBEN to multiplex 10-bit output across D7–D0 (LSBs) and D1/D9 & D0/D8 (MSBs).

Pinout & Package
The MAX1063BEEG is housed in a 24-pin QSOP package (5.3mm × 7.8mm body, 0.635mm pitch), RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 HBEN | High Byte Enable | Selects MSB (D8/D9) vs. LSB (D0–D7) output multiplexing on parallel bus |
| 2–7 D7–D2 | Digital I/O (Tri-State) | Lower 6 bits of 10-bit result; high-impedance when CS high or RD inactive |
| 8 D1/D9 | Digital I/O (Tri-State) | Bit 1 (LSB mode) or bit 9 (MSB mode); shared pin for space-constrained layout |
| 9 D0/D8 | Digital I/O (Tri-State) | Bit 0 (LSB mode) or bit 8 (MSB mode); enables 10-bit read in two cycles |
| 10 INT | Interrupt Output | Active-low signal indicating conversion completion and data validity |
| 11 RD | Read Strobe Input | Falling edge latches valid conversion data onto D7–D0 bus when CS low |
| 12 WR | Write Strobe Input | Rising edge writes control byte (channel, mode, polarity) and triggers acquisition/conversion |
| 13 CLK | Clock Input/Output | Driven externally (100kHz–4.8MHz) or tied high/low for internal clock mode |
| 14 CS | Chip Select | Active-low enable; places all digital outputs in high-Z state when deasserted |
| 15–18 CH3–CH0 | Analog Input Channels | Single-ended inputs; also form pseudo-differential pairs (CH0/CH1, CH2/CH3) |
| 19 COM | Analog Common Reference | Zero-code reference point; must remain stable to ±0.5 LSB during conversion |
| 20 GND | Analog & Digital Ground | Common return for analog and digital sections; requires low-inductance connection |
| 21 REFADJ | Reference Adjust/Bypass | Connect to VDD to disable internal reference; bypass with 0.01µF to GND otherwise |
| 22 REF | Reference Output/Input | Provides +2.5V internal reference; requires 4.7µF capacitor to GND when enabled |
| 23 VDD | Analog Power Supply | +2.7V to +3.6V analog rail; bypass with 0.1µF ceramic capacitor close to pin |
| 24 VLOGIC | Digital I/O Supply | +1.8V to +3.6V logic rail; sets output voltage levels independently of VDD |
Key Features
| Feature | Design Value |
|---|---|
| Software-configurable analog input | Runtime selection of unipolar/bipolar and single-ended/pseudo-differential modes via control byte |
| Low-power operation | 1.9mA at full 250ksps rate; drops to 2µA in shutdown-enables battery life extension in portable medical devices |
| Flexible digital interface | VLOGIC pin decouples I/O voltage from analog supply, allowing seamless integration with 1.8V/2.5V/3.3V microcontrollers |
| Integrated reference | +2.5V internal reference with ±20ppm/°C drift eliminates need for external precision reference in cost-sensitive designs |
| Fast wake-up | 2µs transition from shutdown to first valid conversion-critical for duty-cycled sensor nodes in energy management systems |
| Small footprint | 24-pin QSOP (7.8mm × 5.3mm) saves PCB area versus comparable 28-pin alternatives like MAX1061 |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10-bit SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS7822U | 8-bit resolution, SPI interface, no internal reference, 200ksps max rate | Lacks 10-bit precision and parallel throughput; requires external reference and level-shifting for 1.8V logic | Choose only if 8-bit resolution suffices and SPI interface is preferred over parallel bus. |
| MAX11100ETE+ | 12-bit resolution, 500ksps, internal 2.048V reference, 16-pin TQFN | Higher resolution and speed but larger code size; different pinout and no HBEN multiplexing | Select when >10-bit accuracy is required and board space allows TQFN; not drop-in compatible. |
Compared with ADS7822U and MAX11100ETE+, the MAX1063BEEG uniquely balances 10-bit precision, 250ksps parallel throughput, integrated +2.5V reference, and 24-pin QSOP compactness-making it optimal for space-constrained, battery-powered data-acquisition systems needing deterministic timing and minimal external components.

FAQ
What is the operating temperature range for the MAX1063BEEG?
The MAX1063BEEG is rated for industrial operation from -40°C to +85°C, as indicated by the "E" suffix in its part number. This extended temperature range ensures reliable performance in harsh environments such as factory automation equipment, outdoor energy meters, and portable medical devices deployed across diverse climates. All specified electrical characteristics-including INL (±1 LSB), gain error (±2 LSB), and reference voltage (2.49V–2.51V)-are guaranteed across this full range.
How does the HBEN pin function in the MAX1063BEEG?
The HBEN (High Byte Enable) pin on the MAX1063BEEG controls multiplexing of the 10-bit conversion result across the 8-bit parallel bus. When HBEN = 0, D7–D0 carry the 8 LSBs; when HBEN = 1, D1/D9 and D0/D8 output bits 9 and 8 respectively, while D7–D2 retain their standard assignment. This dual-cycle read mechanism allows full 10-bit access without requiring a wider bus, preserving PCB layout efficiency in resource-constrained designs using the MAX1063BEEG.
Can the MAX1063BEEG operate with an external reference?
Yes, the MAX1063BEEG supports external reference operation. To disable the internal +2.5V reference, connect REFADJ to VDD and apply the external reference voltage to the REF pin. The device accepts reference voltages from 1.0V to VDD + 50mV, and the REF pin exhibits 12pF input capacitance requiring appropriate bypassing. External reference usage maintains all timing and interface functionality of the MAX1063BEEG while enabling higher-precision or ratiometric measurement configurations.
What are the power-down modes available on the MAX1063BEEG?
The MAX1063BEEG offers two software-selectable power-down modes controlled by PD0/PD1 bits in the control byte: standby mode (10µA supply current, retains configuration and reference) and full power-down mode (2µA, disables internal reference and clock). Both modes allow wake-up in 2µs upon WR assertion. These low-current states make the MAX1063BEEG especially suitable for battery-powered applications where duty-cycled sampling is used to maximize operational lifetime.
Is the MAX1063BEEG pin-compatible with other devices in the MAX106x family?
No, the MAX1063BEEG is not pin-compatible with the MAX1061 series-it uses a 24-pin QSOP package versus the MAX1061's 28-pin QSOP. While both share identical functional architecture and control byte structure, the reduced pin count reflects the MAX1063BEEG's 4-channel (vs. 8-channel) analog input capability. Direct replacement would require PCB redesign; however, firmware and interface logic for the MAX1063BEEG remain fully reusable in systems scaled for lower channel count.
