Texas Instruments THS10082IDA

Overview

THS10082IDA from Texas Instruments is a 10-bit, 8 MSPS dual-channel simultaneous-sampling analog-to-digital converter (ADC) with integrated 16-word FIFO, internal 1.5 V/3.5 V reference, ±1 LSB INL/DNL, and 59 dB SINAD at 2 MHz input. It operates on 5-V analog and 3.3-V digital supplies, supporting single-ended or differential inputs for radar front-ends and high-speed DSP acquisition.

For engineers reviewing the THS10082IDA datasheet, THS10082IDA pinout, THS10082IDA application, or THS10082IDA equivalent, key selection criteria include simultaneous dual-channel sampling capability, FIFO depth for burst data handling, internal reference accuracy (±5%, 50 ppm/°C), and compatibility with 3-V/5-V µC/DSP interfaces in industrial temperature range (−40°C to 85°C).

Technical Context

The THS10082IDA employs a multistage pipelined ADC architecture with output error correction logic to guarantee no missing codes across its full operating temperature range. Its dual analog inputs support independent configuration as single-ended or differential channels, enabling flexible signal conditioning in mixed-mode systems.

Two conversion modes are supported: single-conversion mode using an internal oscillator (up to 4 MSPS per channel), and continuous-conversion mode driven by an external CONV_CLK (up to 8 MSPS for one channel or 4 MSPS per channel for two). The integrated FIFO buffers converted data to reduce processor interrupt load and simplify timing-critical read operations.

FAQ

What is the maximum sampling rate per channel for THS10082IDA in continuous conversion mode?

The THS10082IDA achieves 8 MSPS per channel when configured for a single analog input in continuous conversion mode. With two channels enabled (either two single-ended or one differential pair), the maximum sustained rate drops to 4 MSPS per channel due to pipeline arbitration and FIFO write constraints. This behavior is explicitly defined in Table 1 of the datasheet and confirmed by timing diagrams Figure 27 and Figure 28.

Does THS10082IDA support differential input configurations?

Yes, THS10082IDA supports differential input via the AINP and AINM pins. When configured in differential mode, it delivers 59 dB SINAD at 2 MHz and 9.5-bit ENOB-superior to single-ended operation. The device accepts differential input voltages up to ±2 V (REFP − REFM), and internal common-mode bias is set by the REFIN pin, which should be tied to REFOUT per datasheet guidance.

How does the integrated FIFO in THS10082IDA improve system-level timing?

The 16-word FIFO in THS10082IDA decouples conversion timing from host read timing, allowing the processor to fetch data at its own pace without missing samples. In continuous mode, DATA_AV asserts after (7 + TL) CONV_CLK cycles, providing predictable latency. For trigger level = 1, this yields deterministic 8-cycle delay-enabling tight synchronization with DMA engines or interrupt-driven firmware without cycle-counting overhead.

Can THS10082IDA operate with an external reference voltage?

Yes, THS10082IDA supports external reference via REFP and REFM pins. When control register bit 0 is set, the internal reference is disabled and external voltages (e.g., precision 2.5 V reference) can be applied. Datasheet Section 15 confirms external reference selection is programmable, and REFP must remain within AVDD − 1.2 V to ensure proper ADC headroom and linearity.

What is the operating temperature range specified for THS10082IDA?

THS10082IDA is characterized for operation from −40°C to +85°C ambient temperature, as stated in the Ordering Information table and Absolute Maximum Ratings section. This industrial-grade rating is validated across all AC and DC specifications-including SINAD, INL, DNL, and reference drift-making it suitable for under-hood automotive and factory-floor industrial deployments.
