Product Overview
Maxim MAX186CCPP is a 12-bit successive approximation register (SAR) analog-to-digital converter packaged in a standard 20-pin narrow plastic DIP. It features an internal 8-channel multiplexer configurable by software for single-ended or differential operation, as well as unipolar or bipolar inputs. With an internal 4.096 V reference, serial SPI/QSPI/MICROWIRE compatibility, and sampling rates up to 133 ksps, it serves instrumentation, automated testing, and benchtop data acquisition setups.
Key Features
- 12-bit SAR analog-to-digital conversion at up to 133 ksps
- 8-channel analog input multiplexer software-configurable for single-ended or differential modes
- Built-in +4.096 V reference with internal buffer
- 4-wire serial interface compatible with SPI, QSPI, and MICROWIRE standards
- Operates from a single +5 V supply or dual ±5 V supplies
- Commercial operating temperature range (0°C to +70°C)
- Standard 20-pin narrow DIP (0.300-inch body width) through-hole package
Applications
- Digitizing multi-channel sensor arrays on microcontrollers or breadboards without dedicated analog inputs
- Upgrading or servicing legacy industrial automation boards and analog measurement instrumentation
- Prototyping precision data logging circuits requiring flexible unipolar and bipolar ranges
Frequently Asked Questions
Can the analog inputs measure negative voltages?
Yes. When powered with dual ±5 V supplies, the input multiplexer can be software-configured for bipolar input ranges.
Is an external voltage reference required for operation?
No. The MAX186 includes an internal +4.096 V reference and reference buffer, though an external reference can also be connected if required by your circuit.
How does the MAX186 communicate with a host microcontroller?
It uses a standard 4-wire synchronous serial interface compatible with SPI, QSPI, and MICROWIRE protocols.
What pin spacing and body width does this package use?
It is a standard 20-pin narrow DIP with 0.100-inch (2.54 mm) pin pitch and 0.300-inch (7.62 mm) row spacing, fitting standard breadboards and IC sockets.
Eight channels of 12-bit precision ready to drop into a standard breadboard or socket without surface-mount adapters. For analog prototyping and quiet measurement circuits, this converter delivers straightforward numbers.
