ADC08062CIWM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC08062CIWM/NOPB is an obsolete 8-bit analog-to-digital converter featuring a two-channel multiplexer and internal sample-and-hold. It utilizes a patented multi-step flash conversion technique to achieve a maximum conversion time of 560 ns in WR-RD mode, supporting a throughput rate of 1.5 MHz. The device operates on a single +5V supply with a power consumption of 100 mW max. Key specifications include a full-power bandwidth of 300 kHz, tri-state digital outputs, and flexible interface modes (RD or WR-RD). The CIWM variant specifies a Total Unadjusted Error (TUE) of ±1 LSB.

Analog To Digital Converters (ADC) Feature Summary

• Two-channel input multiplexer selectable via A0 pin
• Internal sample-and-hold circuitry eliminates external S/H requirements
• Tri-state digital outputs for direct microprocessor interfacing
• Overflow output (OFL) available for cascading higher resolution systems

Analog To Digital Converters (ADC) Applications

• Mobile telecommunications signal processing
• Hard disk drive read channel data acquisition
• High-speed instrumentation systems
• General-purpose data acquisition applications

Analog To Digital Converters (ADC) Procurement Notes

This component is officially designated as obsolete by Texas Instruments. Verify availability through authorized distributors for remaining stock or consider active replacement alternatives. Ensure the specific CIWM suffix matches the required ±1 LSB linearity specification rather than the BIN grade.

Analog To Digital Converters (ADC) Selection Notes

Select this part when a low-cost, single-supply 8-bit ADC with integrated multiplexing is required. The CIWM package offers a wider operating temperature range (-40°C to 85°C) compared to the BIN grade. Note that the device requires a minimum reference span of 2.0V for optimal linearity performance.

Analog To Digital Converters (ADC) Part Context

The ADC08062 is the dual-channel version of the ADC08061 family. While the ADC08061 provides a single input, the ADC08062 integrates a 2:1 multiplexer controlled by the A0 logic pin. Both share identical conversion architecture, timing characteristics, and pinouts, differing only in analog input count.

Analog To Digital Converters (ADC) Replacement Considerations

As an obsolete product, no direct functional equivalents are listed in the primary datasheet. Designers should evaluate modern high-speed SAR ADCs from current TI portfolios that offer similar throughput rates and multiplexed inputs.
