Product details
Overview
MAX166CCPP+ from Maxim Integrated is a 12-bit analog-to-digital converter (ADC) with parallel interface, internal reference, and ±5V input range, operating from a single +5V supply. It features 100ksps sampling rate, 0.5 LSB integral nonlinearity (INL), and CMOS-compatible digital outputs for embedded data acquisition systems.
For engineers reviewing the MAX166CCPP+ datasheet, MAX166CCPP+ pinout, MAX166CCPP+ application, or MAX166CCPP+ equivalent, key selection considerations include its 12-bit resolution, parallel 8-bit byte-mode output architecture, internal 2.5V reference, and operation over 0°C to +70°C commercial temperature range.
Technical Context
The MAX166CCPP+ employs a successive-approximation register (SAR) architecture with track-and-hold circuitry, enabling accurate DC and low-frequency AC signal conversion. Its internal 2.5V bandgap reference ensures stable full-scale calibration without external components.
Digital interface uses an 8-bit byte-wide parallel bus with separate BUSY, RD, and WR control signals, supporting direct connection to microcontrollers and DSPs without glue logic. Conversion timing is controlled by internal clock generator synchronized to WR pulse.

| RD | Read Strobe Input | Active-low signal that latches conversion result into output registers and enables data transfer to host |
| WR | Write Strobe Input | Active-low signal initiating conversion start and resetting internal state machine |
| BUSY | Conversion Status Output | Active-high open-drain signal indicating ongoing conversion; used for polling or interrupt-driven timing |
| VREF | Reference Voltage Input/Output | Internally connected to 2.5V bandgap; can be overdriven externally to set custom full-scale range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 12-bit parallel-output ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7823ANZ | 8-bit resolution, SPI interface, no internal reference - requires external 2.5V reference and serial interface logic | Suited for space-constrained designs where serial interface and lower resolution are acceptable | Select AD7823ANZ when board area is critical and 8-bit accuracy suffices for cost-sensitive consumer sensors |
| MAX195BCPP+ | 16-bit resolution, serial interface, ±10V input range, external reference required - higher precision but greater system complexity | Targeted at high-end instrumentation requiring <0.0015% full-scale error and wider dynamic range | Select MAX195BCPP+ when absolute accuracy and extended input range outweigh interface simplicity and BOM cost |
Compared with AD7823ANZ and MAX195BCPP+, the MAX166CCPP+ uniquely balances 12-bit accuracy, parallel byte-mode interface, and integrated reference-making it optimal for mid-tier industrial controllers where ease of microcontroller integration and moderate precision are jointly prioritized.

FAQ
What is the maximum sampling rate supported by the MAX166CCPP+?
The MAX166CCPP+ supports a maximum sampling rate of 100 kSPS (kilo-samples per second). This rate is guaranteed across the full 0°C to +70°C operating temperature range and with the internal reference enabled. The conversion time is fixed at 10 µs per sample, and the BUSY signal remains asserted for this duration to indicate active conversion.
Does the MAX166CCPP+ require an external reference voltage?
No, the MAX166CCPP+ includes an internal 2.5V bandgap reference with ±0.5% initial accuracy. This reference is connected internally to the VREF pin and provides full-scale calibration without external components. However, the VREF pin can be overdriven with an external precision reference if tighter accuracy or custom full-scale ranges are required.
How is the 12-bit result transferred via the parallel interface of the MAX166CCPP+?
The MAX166CCPP+ transfers its 12-bit result in two consecutive 8-bit bytes using the DB0–DB7 bus. After conversion completes, the first RD pulse outputs the LSB byte (bits 0–7); the second RD pulse outputs the MSB byte (bits 8–11, aligned to DB0–DB3). DB4–DB7 read as zero during the MSB cycle.
What is the input voltage range specification for the MAX166CCPP+?
The MAX166CCPP+ accepts a differential input voltage range of ±5V relative to AGND. This bipolar range allows direct connection to op-amp-based signal conditioning stages without level-shifting circuitry. The device maintains specified INL and gain error performance across the full ±5V span when operated with the internal 2.5V reference.
Is the MAX166CCPP+ compatible with 3.3V logic systems?
The MAX166CCPP+ is designed for +5V digital supply and TTL/CMOS-compatible logic levels. Its RD, WR, and BUSY signals operate at 5V logic thresholds and are not 3.3V-tolerant. Interfacing with 3.3V microcontrollers requires level-shifting on control lines and careful management of the DB0–DB7 bus to avoid overvoltage damage or logic misreads.
