Texas Instruments ADC08200CIMT

Overview

ADC08200CIMT from Texas Instruments is an 8-bit, 200 Msps monolithic analog-to-digital converter with integrated sample-and-hold, single-ended input, +3V supply operation, and TTL/CMOS-compatible digital outputs. It delivers 7.3 ENOB at 50 MHz input frequency, consumes 210 mW at full rate, and supports industrial temperature range (−40°C to +105°C) in a 24-lead TSSOP package - used in flat panel displays and medical imaging front-ends.

For engineers reviewing the ADC08200CIMT datasheet, ADC08200CIMT pinout, ADC08200CIMT application, or ADC08200CIMT equivalent, this page provides verified technical context, real-world timing behavior (6-cycle pipeline latency, 2.6 ns aperture delay), power-down functionality (1 mW), reference ladder interface (VRT/VRB/VRM), and validated alternatives for high-speed 8-bit sampling systems.

Technical Context

The ADC08200CIMT employs a unique switched-capacitor bandgap architecture optimized for low-power, high-speed conversion up to 230 Msps. Its internal track-and-hold enables stable sampling at 200 Msps with 2 ps rms aperture jitter and 500 MHz full-power bandwidth.

It uses straight-binary output coding with separate VDR supply for 2.5V/3V logic interfacing, and features a 6-clock-cycle pipeline latency plus output delay (tOD ≤ 5.1 ns). The reference ladder's top (VRT), bottom (VRB), and midpoint (VRM) pins allow flexible input range configuration between 0.3 V and 1.9 V.

FAQ

What is the maximum sampling rate guaranteed for ADC08200CIMT across its full temperature range?

The ADC08200CIMT is specified for a minimum sampling rate of 200 Msps over the industrial temperature range of −40°C to +105°C. This is confirmed in the Electrical Characteristics table under "Maximum Conversion Rate (fC1)" with boldface limits applying across TJ = TMIN to TMAX. At 25°C, it can operate up to 230 Msps, but 200 Msps is the guaranteed minimum across the full operating range.

Does ADC08200CIMT require an external sample-and-hold circuit?

No, ADC08200CIMT does not require an external sample-and-hold circuit. It integrates a fully functional on-chip track-and-hold (T/H) circuit, explicitly stated in the device description and featured as "Internal Sample-and-Hold Function." This eliminates external components and reduces layout complexity for high-frequency analog input paths.

What is the purpose of the VRM pin on ADC08200CIMT?

The VRM pin on ADC08200CIMT is the midpoint of the internal reference voltage ladder. It must be bypassed to a quiet ground point with a 0.1 µF capacitor and should not be loaded with more than 10 µA. It enables stable mid-scale biasing for AC-coupled inputs and improves common-mode rejection in differential reference configurations.

Can ADC08200CIMT interface directly with 2.5V logic systems?

Yes, ADC08200CIMT can interface directly with 2.5V logic systems using its dedicated VDR (output driver supply) pin. The digital outputs D0–D7 are TTL/CMOS compatible and support VDR from +2.4V to VA, allowing VDR to be set at 2.5V while VA remains at +3.0V - enabling seamless 2.5V logic interfacing without level shifters.

What is the pipeline latency of ADC08200CIMT, and how does it affect system timing?

The ADC08200CIMT has a fixed pipeline delay of 6 clock cycles, as specified in the AC Electrical Characteristics table. This means data acquired on a given CLK edge appears at the D0–D7 outputs after 6 full clock periods plus output delay (tOD ≤ 5.1 ns). This deterministic latency simplifies timing closure in FPGA-based capture systems and enables precise synchronization with downstream processing stages.
