ADC08L060CIMT/NOPB

Analog To Digital Converters (ADC) Overview

The ADC08L060CIMT/NOPB is an 8-bit, monolithic analog-to-digital converter manufactured by Texas Instruments. It features a pipeline architecture with an internal sample-and-hold circuit, supporting conversion rates from 10 MSPS to 60 MSPS. The device operates on a single +3V supply, consuming approximately 0.65 mW per MHz of clock frequency (39 mW at 60 MSPS). Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 48 dB and an Effective Number of Bits (ENOB) of 7.6 bits at 10.1 MHz input. It utilizes a parallel CMOS/TTL-compatible interface and is housed in a 24-lead TSSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component authenticity through authorized Texas Instruments distributors or certified suppliers. Confirm that the part matches the SNAS167G datasheet revision. Ensure the ordering suffix /NOPB indicates lead-free packaging compliant with RoHS standards. Check for physical damage to the TSSOP-24 leads before integration into the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and up to 60 MSPS sampling rate are required within a low-power constraint. The ADC08L060 requires external reference voltages applied to VRT and VRB pins to define the input range; ensure the driving source can handle the reference ladder current. Verify that the system clock duty cycle remains between 5% and 95% for optimal timing performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC08L060 series produced by Texas Instruments. It is a successor to earlier National Semiconductor designs acquired by TI. The /NOPB suffix specifically denotes a lead-free product that adheres to environmental directives. The device is specified for industrial temperature ranges from -40°C to +85°C.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADC08L060CIMTX/NOPB. Other variants such as the ADC08L060CIMT/NOPB share identical electrical characteristics but may differ in tape-and-reel packaging versus tube packaging. Cross-family replacements require careful evaluation of latency and interface compatibility.

Analog To Digital Converters (ADC) FAQ

How is the analog input voltage range determined?

The input voltage range is defined by the external voltages applied to the VRT (top reference) and VRB (bottom reference) pins. The VIN signal must remain between these two levels for accurate digitization.

What is the digital latency of the ADC08L060?

The device has a pipeline delay of 5 clock cycles. Valid data appears at the output pins after the rising edge of the clock plus the output delay time (tOD).

Can the output drivers operate with 1.8V logic?

Yes, the ADC08L060 features a separate output driver supply pin (VDR). Connecting VDR to a voltage between 1.8V and VA allows the digital outputs to interface directly with 1.8V logic families.
