Texas Instruments THS10082CDA

Overview

THS10082CDA from Texas Instruments is a 10-bit, 8 MSPS dual-channel simultaneous-sampling analog-to-digital converter (ADC) with integrated 16-word FIFO, 5-V analog/3.3-V digital supply operation, ±1 LSB DNL/INL, and 59 dB SINAD at 2 MHz input - deployed in radar front-ends, high-speed DSP acquisition, and automotive sensor signal conditioning.

For engineers reviewing the THS10082CDA datasheet, THS10082CDA pinout, THS10082CDA application, or THS10082CDA equivalent, key selection criteria include simultaneous dual-input sampling capability, internal/external reference flexibility (1.5 V / 3.5 V or external), single-ended/differential configuration support, and FIFO-triggered interrupt handling for real-time data flow control.

Technical Context

The THS10082CDA employs a multistage pipelined ADC architecture with output error correction logic to guarantee no missing codes across 0°C to 70°C. It supports two conversion modes: internally clocked single-conversion mode (up to 4 MSPS per channel) and externally clocked continuous mode (up to 8 MSPS for one channel or 4 MSPS per channel for two).

Its analog inputs (AINP/AINM) are configurable as either two independent single-ended channels or one differential pair, with programmable auto-scan sequencing. The integrated FIFO uses write/read/trigger pointers to manage circular-buffer data flow, reducing processor interrupt load during burst acquisition.

FAQ

What is the maximum sampling rate of the THS10082CDA in continuous conversion mode?

The THS10082CDA achieves 8 MSPS when sampling a single analog channel (either single-ended or differential) in continuous conversion mode. With two channels enabled, the maximum sustained rate per channel drops to 4 MSPS due to interleaved pipeline timing - verified in Table 1 of the SLAS254B datasheet under "Maximum Conversion Rate in Continuous Conversion Mode." This behavior is inherent to its dual-channel pipelined architecture and applies to both THS10082CDA and THS10082IDA variants.

Does the THS10082CDA support differential input configuration?

Yes, the THS10082CDA supports true differential input using the AINP and AINM pins, enabling common-mode noise rejection and improved SNR. In differential mode, full-scale input range is defined by VREFP − VREFM (2 V), yielding 59 dB SINAD and 65 dB SFDR at 2 MHz - 1–2 dB better than single-ended operation. Configuration is controlled via internal registers and requires proper external termination per Figure 25 in the datasheet.

How does the integrated FIFO in the THS10082CDA reduce processor overhead?

The THS10082CDA's 16-word FIFO acts as a hardware buffer that stores converted samples before host readout. By configuring DATA_AV to assert at user-defined trigger levels (e.g., 4 or 8 words), the processor receives fewer, larger bursts of data - cutting interrupt frequency and eliminating tight timing constraints on individual sample reads. This is especially valuable in resource-constrained µC systems interfacing via parallel bus.

Can the THS10082CDA operate with an external reference voltage?

Yes, the THS10082CDA accepts external reference voltages applied to REFP and REFM pins, overriding the internal 3.5 V / 1.5 V references. This is selected via Control Register 0 (bit 6). External referencing improves dc accuracy and temperature drift performance - critical in precision measurement applications - but requires stable, low-noise sources and 10 µF AGND bypassing per the datasheet layout guidelines.

What is the operating temperature range for the THS10082CDA?

The THS10082CDA is characterized for operation from 0°C to 70°C ambient temperature, as specified in the Ordering Information table and Recommended Operating Conditions section of SLAS254B. This commercial-grade rating distinguishes it from the THS10082IDA (−40°C to 85°C), and all electrical specifications - including SINAD, INL, and power consumption - are guaranteed within this range.
