ADC12130CIN/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12130CIN/NOPB is a self-calibrating, 12-bit plus sign successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a configurable input multiplexer and sample/hold circuitry, supporting serial I/O protocols including MICROWIRE, SPI, and QSPI. The device operates on a single +3.3V or +5V supply with power consumption of 15 mW at 3.3V and 33 mW at 5V. Key electrical specifications include a maximum conversion time of 8.8 μs, a throughput rate of approximately 71.4 kSPS, and an integral linearity error of ±2 LSB after auto-calibration. It is housed in a 28-pin MDIP package.

Analog To Digital Converters (ADC) Feature Summary

• Self-Calibrating Architecture: Automatically adjusts linearity, zero, and full-scale errors to typically less than ±1 LSB without external adjustment components.
• Flexible Input Multiplexer: Includes a two-channel multiplexer with outputs available on MUXOUT pins for external buffering or filtering.
• Serial Interface Compatibility: Supports NSC-MICROWIRE, SPI, and QSPI compatible serial I/O with programmable output word length and format.
• Low Power Operation: Consumes 15 mW (max) at 3.3V and 33 mW (max) at 5V, with power down currents as low as 20 μA.

Analog To Digital Converters (ADC) Applications

• Pen-based computers and portable data terminals
• Industrial digitizers and signal acquisition systems
• Global positioning systems (GPS) receiver front-ends

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIN' corresponds to the 28-pin MDIP package and commercial temperature range (-40°C to +85°C). Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance. Check current production status, as older PDIP packages may be subject to obsolescence notices from the manufacturer.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-supply, self-calibrating ADC with a built-in multiplexer is required. Ensure the system clock frequency does not exceed 5 MHz. Verify that the analog input voltage range (0V to VREF+) aligns with the application's signal levels. Consider the 28-pin DIP footprint constraints during PCB layout.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12130 family, which also includes the ADC12132 (2-channel MUX) and ADC12138 (8-channel MUX). All variants share identical core ADC performance and pinouts for the conversion interface, differing primarily in the number of available multiplexer channels. The CIN suffix specifically denotes the through-hole MDIP packaging option.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same family include the ADC12132 and ADC12138, provided the channel count meets design requirements. For legacy National Semiconductor equivalents, verify compatibility with the original ADC12130 datasheet specifications before substitution.
