Product details
Overview
MAX1060BCEI+T from Maxim Integrated is a 10-bit successive-approximation ADC with 8-channel single-ended or 4-channel pseudo-differential analog input, +2.5V internal reference, byte-wide parallel (8+2) interface, and 400ksps max sampling rate. 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 microcontrollers in portable data-acquisition systems.
For engineers reviewing the MAX1060BCEI+T datasheet, MAX1060BCEI+T pinout, MAX1060BCEI+T application, or MAX1060BCEI+T equivalent, key selection criteria include its ±0.5 LSB INL at 0°C to +70°C, software-configurable unipolar/bipolar input mode, fast 2µs wake-up from shutdown, and QSOP-28 package compatibility with industrial sensor front-ends and battery-powered medical monitors.
Technical Context
The MAX1060BCEI+T implements a capacitive charge-redistribution SAR architecture with integrated track-and-hold, supporting both internal and external clock modes. Its analog input multiplexer is software-configured for single-ended (CH0–CH7) or pseudo-differential (CH0/CH1, CH2/CH3, CH4/CH5, CH6/CH7) operation, with COM serving as the stable reference node.
Conversion timing is controlled via WR and CS signals, with ACQMOD bit selection enabling either internally timed acquisition (~1µs in internal clock mode) or user-controlled external acquisition. The device features two power-down modes-standby (≤10µA) and full shutdown (≤2µA)-activated by PD0/PD1 bits in the control byte, and uses HBEN to multiplex 10-bit output across an 8-bit data bus.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit SAR with no missing codes over temperature - ensures monotonicity in closed-loop control feedback paths. |
| Sampling Rate | Up to 400ksps - supports real-time monitoring of 175kHz sinusoidal inputs with >56dB SINAD. |
| INL / DNL | ±0.5 LSB / ±1 LSB - enables accurate DC measurement in energy metering and industrial transducer interfaces. |
| Reference | +2.5V internal bandgap reference (±20ppm/°C TC, ±100mV adjust range) - eliminates external reference component count. |
| Power Consumption | 2.5mA at 400ksps, ≤2µA in shutdown - extends battery life in portable patient monitors and handheld test equipment. |
| Analog Input Range | Unipolar: 0 to +2.5V; Bipolar: −1.25V to +1.25V - accommodates both sensor outputs and differential signal conditioning stages. |
| Full-Power Bandwidth | 6MHz - allows undersampling of RF or transient signals beyond Nyquist limit in spectrum analysis applications. |
Pinout & Package
MAX1060BCEI+T is housed in a 28-pin QSOP (Quad Small Outline Package) with 3.9mm body width and 0.635mm lead pitch, optimized for high-density PCB layouts in space-constrained instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HBEN | High-byte enable control | Selects whether D0–D7 carry LSBs (HBEN=0) or MSBs (HBEN=1), enabling 10-bit readout over 8-bit bus without external latching. |
| D0/D8, D1/D9 | Multiplexed bidirectional data I/O | Shares physical pins for 8-bit data bus and two high-order bits - reduces interface wiring while maintaining full resolution. |
| INT | Open-drain conversion-complete flag | Asserts low asynchronously upon result readiness, allowing interrupt-driven µP polling without continuous status checking. |
| WR, RD, CS | Parallel interface handshaking | Standard 8080-style control signals - simplifies integration with legacy microcontrollers and FPGA-based data capture logic. |
| CH0–CH7 | Analog input channels | Eight single-ended inputs or four pseudo-differential pairs - supports multi-sensor acquisition in PLC I/O modules and environmental monitoring nodes. |
| VLOGIC | Digital supply rail | Independent +2.7V to +5.5V logic supply - decouples digital noise from analog section and enables mixed-voltage system interoperability. |
| REF, REFADJ | Internal reference buffer | Provides stable +2.5V reference with 4.7µF bypass; REFADJ allows trimming or disabling for external reference use. |
Key Features
| Feature | Design Value |
|---|---|
| Software-configurable input topology | Single-ended (8 ch) or pseudo-differential (4 ch) mode selected via SGL/DIF bit - eliminates need for external multiplexer in multi-signal systems. |
| Adjustable logic-level interface | VLOGIC pin accepts +2.7V to +5.5V - permits direct connection to 3.3V or 5V µPs without level shifters in hybrid digital/analog subsystems. |
| Low-power shutdown states | Standby (≤10µA) and full shutdown (≤2µA) modes - enables duty-cycled operation in battery-powered IoT edge nodes with <1µA average current. |
| Integrated track-and-hold | 6MHz full-power bandwidth with 3.2µs acquisition time - supports accurate sampling of fast-rising transients without external THS circuitry. |
| Flexible clock architecture | Internal 7.6MHz clock or external 100kHz–7.6MHz source - relieves µP timing burden while retaining precise aperture control via external acquisition mode. |

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 |
|---|---|---|---|
| MAX1061BCEI+T | +3V supply only (VDD = VLOGIC = +3V); identical pinout and feature set except lower supply voltage range. | Suitable for 3.3V-only systems where level translation is undesirable; not compatible with mixed 5V analog/3.3V digital domains. | Select MAX1061BCEI+T when system uses single +3.3V rail and requires identical functionality with reduced power draw. |
| ADS7822U | 8-bit resolution, SPI interface, no internal reference; 200ksps max rate; SO-8 package. | Targeted at cost-sensitive, low-pin-count applications where 10-bit precision and parallel throughput are not required. | Choose ADS7822U only for space-constrained designs accepting 8-bit resolution and willing to trade parallel speed for serial simplicity. |
Compared with MAX1060BCEI+T, MAX1061BCEI+T offers identical functionality at +3V but lacks 5V analog compatibility, while ADS7822U sacrifices 2 bits of resolution, halved sampling rate, and parallel interface - making MAX1060BCEI+T the optimal choice for 10-bit, 400ksps, mixed-voltage industrial data acquisition.

FAQ
What is the operating temperature range for MAX1060BCEI+T?
The MAX1060BCEI+T is specified for operation from 0°C to +70°C, as indicated by the 'C' grade suffix in its ordering code. This commercial-grade temperature range is validated per the device's Absolute Maximum Ratings and Electrical Characteristics tables, with performance parameters including ±0.5 LSB INL and 400ksps sampling rate guaranteed across the full span.
Does MAX1060BCEI+T require an external clock to operate?
No, MAX1060BCEI+T does not require an external clock. It includes an internal 7.6MHz oscillator that can be selected via control byte bits D7/D6. When using internal clock mode, the CLK pin must be tied to VDD or GND to prevent floating; external clock mode (100kHz–7.6MHz) is optional and used when precise aperture timing control is needed.
How many analog input channels does MAX1060BCEI+T support?
MAX1060BCEI+T supports eight single-ended analog input channels (CH0–CH7) or four pseudo-differential channel pairs (CH0/CH1, CH2/CH3, CH4/CH5, CH6/CH7), as confirmed in the Pin Configurations diagram and General Description. This 8-/4-channel capability is fixed for the MAX1060 family and distinct from the 4-/2-channel MAX1064 variant.
Can MAX1060BCEI+T interface directly with a 3.3V microcontroller?
Yes, MAX1060BCEI+T can interface directly with a 3.3V microcontroller via its VLOGIC pin, which accepts +2.7V to +5.5V digital supply voltage. When VLOGIC = 3.3V, the device's D0–D7 outputs swing between 0V and 3.3V, matching standard 3.3V logic thresholds without level-shifting circuitry.
What is the purpose of the HBEN pin on MAX1060BCEI+T?
The HBEN (High-Byte Enable) pin on MAX1060BCEI+T 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, D0–D7 carry the eight least significant bits (LSBs). This enables full 10-bit readout using only 8 data lines.
