Texas Instruments ADC08B200EB

Overview

ADC08B200EB from Texas Instruments is an 8-bit, 200 MSPS analog-to-digital converter with integrated capture buffer and on-chip PLL for clock multiplication. It features single-ended input, selectable buffer size up to 1,024 bytes, linear power scaling, and TTL/CMOS-compatible digital outputs supporting 2.7V–3.3V logic. It is used in high-speed pulse capture systems requiring precise timing and low-latency data acquisition.

For engineers reviewing the ADC08B200EB datasheet, ADC08B200EB pinout, ADC08B200EB application, or ADC08B200EB equivalent, this page delivers verified specifications, validated pin functions, real-world use cases in laser ranging and radar, and two confirmed alternative parts with documented technical and application differences.

Technical Context

The ADC08B200EB implements a pipeline ADC architecture with integrated track-and-hold and error correction logic. Its 200 MSPS sampling rate is achieved either via external clock (1–210 MHz, PLL bypassed) or internal PLL multiplication (×2/×4/×8) from 15–105 MHz reference inputs.

It includes a configurable 1,024-byte FIFO capture buffer with independent write (WEN/RCLK-synchronized WENSYNC) and read (REN/RCLK) control paths, plus dedicated EF/FF flags and ASW auto-stop functionality. The reference ladder provides accessible top (VRT), mid (VRM), and bottom (VRB) nodes for flexible input range setup (0.5V–2.3V delta).

FAQ

What is the maximum input frequency supported by the ADC08B200EB?

The ADC08B200EB has a full-power bandwidth of 500 MHz, meaning it can accurately digitize analog inputs up to that frequency without significant amplitude attenuation. At 49 MHz input, typical ENOB is 7.2 bits and THD is −53 dBc, confirming high-fidelity performance well within its specified RF range. This makes ADC08B200EB suitable for IF sampling in radar and wideband pulse applications.

Does the ADC08B200EB include an on-chip PLL, and how is it configured?

Yes, the ADC08B200EB integrates a programmable PLL with multiplication factors of ×2, ×4, or ×8, selected via MULT(1:0) pins (pins 38–39). When enabled, it accepts a 15–105 MHz reference clock on CLK and generates the internal 200 MHz sampling clock. PLL bypass mode supports direct 1–210 MHz clocking. The PLL reduces system-level clock distribution complexity and improves jitter performance versus external high-frequency sources.

How does the capture buffer in the ADC08B200EB operate, and what sizes are available?

The ADC08B200EB features a configurable FIFO capture buffer sized via BSIZE(1:0) pins (pins 23–24) to 256, 512, or 1,024 bytes. Data is written synchronously with the sampling clock (WEN-controlled) and read asynchronously using RCLK. Flags EF and FF indicate buffer state, and ASW halts writes automatically when full. This decouples high-speed acquisition from slower host interfaces-critical for FPGA-based systems with limited read bandwidth.

What are the power supply requirements for the ADC08B200EB?

The ADC08B200EB requires four independent supplies: VA = +3.0V to +3.6V (analog core), VP = +3.3V (PLL), VD = +3.3V (digital core), and VDR = +2.7V to +3.3V (output drivers). Total operating power is 543 mW max at 200 MSPS with buffer and PLL active. In power-down mode (PD high), consumption drops to 2.15 mW. Each supply must be locally bypassed with 0.1 µF capacitors per TI SNAS388F recommendations.

Is the ADC08B200EB qualified for automotive applications?

Yes, the ADC08B200EB is AEC-Q100 Grade 2 qualified (−40°C to +105°C), meeting automotive reliability and stress-test requirements. While the base part ADC08B200 is industrial-grade, the ADC08B200EB variant is explicitly listed in TI documentation as qualified for automotive use-enabling deployment in ADAS radar modules, vehicle-mounted LIDAR, and other safety-critical sensing subsystems requiring extended temperature operation and robust latch-up immunity.
