Texas Instruments ADC08B200CIVS/NOPB

Overview

ADC08B200CIVS/NOPB 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 analog input (VIN), selectable 1024-byte capture buffer, TTL/CMOS-compatible digital outputs (2.7–3.3 V), and operates across −40°C to +105°C. It is used in high-speed pulse capture systems requiring precise timing and low-latency data acquisition.

For engineers reviewing the ADC08B200CIVS/NOPB datasheet, ADC08B200CIVS/NOPB pinout, ADC08B200CIVS/NOPB application, or ADC08B200CIVS/NOPB equivalent, key selection considerations include its 200 MSPS sampling rate, 7.2-bit ENOB at 49 MHz, ±0.4 LSB typical DNL, 500 MHz full-power bandwidth, and TQFP-48 package with separate analog/digital/PLL/output supply domains.

Technical Context

The ADC08B200CIVS/NOPB employs a pipeline architecture with integrated track-and-hold and error correction logic. Its core sampling engine delivers 200 MSPS with aperture jitter as low as 2 ps rms (PLL bypassed) and 7 ps rms (PLL ×8 mode), enabling accurate digitization of fast transient signals.

It integrates a configurable capture buffer (BSIZE[1:0] selects 256/512/1024 bytes) and dual-clock domain control: CLK drives sampling (1–210 MHz, PLL-bypassed), while RCLK controls buffered readout (2–210 MHz). Output timing is synchronized to DRDY with edge-selectable data strobing via OEDGE/TEN.

Key Specifications

Pinout & Package

ADC08B200CIVS/NOPB is housed in a 48-pin TQFP package (PFB0048A), with dedicated supply domains: VA (analog core), VP (PLL), VD (digital core), and VDR (output drivers, 2.7–3.3 V). Ground pins are segregated into SIG GND, DR GND, and core GND to minimize noise coupling.

FAQ

What is the maximum input frequency supported by ADC08B200CIVS/NOPB?

The ADC08B200CIVS/NOPB has a full-power bandwidth of 500 MHz, meaning it can accurately digitize analog inputs up to that frequency at full scale. This specification ensures minimal amplitude roll-off for fast transients and RF signals within its Nyquist zone, making ADC08B200CIVS/NOPB suitable for IF sampling in RADAR and laser ranging applications where signal integrity at high frequencies is critical.

Does ADC08B200CIVS/NOPB support differential input configurations?

No, ADC08B200CIVS/NOPB is specified for single-ended analog input only, with VIN referenced to the VRT–VRB ladder. It does not include internal differential input circuitry or dedicated IN+/IN− pins. Designers requiring differential signaling must implement external transformer or amplifier-based front-end conditioning before connecting to VIN, ensuring common-mode voltage stays within the 0.3 V to 1.9 V range defined by VRB and VRT.

How does the capture buffer in ADC08B200CIVS/NOPB operate during continuous sampling?

The ADC08B200CIVS/NOPB capture buffer operates as a circular FIFO: when enabled via WEN, samples are written at the sampling clock rate (up to 200 MSPS), and when read via RCLK and REN, data is drained synchronously. The BSIZE[1:0] pins configure depth (256/512/1024 bytes), and ASW halts writes when the buffer fills. This allows ADC08B200CIVS/NOPB to absorb high-speed bursts while enabling slower, deterministic host readout - critical for pulse capture without data loss.

What are the supply voltage requirements for ADC08B200CIVS/NOPB?

ADC08B200CIVS/NOPB requires four independent supplies: VA = +3.0 to +3.6 V (analog core), VP = +3.0 to +3.6 V (PLL), VD = +3.0 to +3.6 V (digital core), and VDR = +2.7 to +3.6 V (output drivers). Each supply must be individually bypassed with low-ESR capacitors; mismatched or unregulated supplies degrade ENOB and increase THD. The separation ensures noise isolation between sensitive analog, timing, and digital output domains in ADC08B200CIVS/NOPB.

Is ADC08B200CIVS/NOPB qualified for automotive use?

No - ADC08B200CIVS/NOPB is rated for the extended industrial temperature range (−40°C to +105°C) and is not AEC-Q100 qualified. The automotive-grade variant is ADC08B200Q, which carries AEC-Q100 Grade 2 qualification. For automotive applications requiring qualification, ADC08B200Q must be selected; ADC08B200CIVS/NOPB is intended for industrial, test, and defense systems where extended temperature operation is needed but formal automotive certification is not required.
