ADC12034CIN/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12034CIN/NOPB is a self-calibrating 12-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 4-channel multiplexer supporting differential, pseudo-differential, or single-ended inputs. The device operates on a single +5V supply with a maximum power consumption of 33 mW and includes an integrated sample-and-hold function. It utilizes a MICROWIRE-compatible serial interface for data exchange. Key electrical specifications include a maximum throughput time of 14 µs, integral linearity error of ±1 LSB after auto-calibration, and an operating temperature range from -40°C to +85°C.

• 4-channel analog input multiplexer with configurable single-ended or differential modes
• Self-calibrating architecture that adjusts linearity, zero, and full-scale errors
• MICROWIRE-compatible serial I/O interface with programmable acquisition time

Analog To Digital Converters (ADC) Applications

• Medical instruments
• Process control systems
• Test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify component status as the ADC12034 family may be obsolete or subject to lifetime buy restrictions. Confirm package integrity for the 24-pin DIP format upon receipt. Ensure external reference voltages meet the specified impedance requirements to maintain accuracy during operation.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 4-channel multiplexed input is required alongside 12-bit precision. The ADC12034 differs from the ADC12030 family by its internal 4-channel multiplexer configuration. Ensure the application supports the 5V logic levels and serial clock frequencies up to 5 MHz for optimal performance within the specified thermal limits.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC12(H)030/2/4/8 family of self-calibrating A/D converters. The 'C' suffix indicates the commercial temperature grade (-40°C to +85°C), while 'IN' designates the 24-pin wide body PDIP package. The '/NOPB' suffix confirms compliance with RoHS standards and absence of lead-based materials.
