Texas Instruments ADC08200CIMTX/NOPB

Overview

ADC08200CIMTX/NOPB from Texas Instruments is an 8-bit, 200 Msps monolithic analog-to-digital converter with internal sample-and-hold, single-ended input, +3V supply operation, and TTL/CMOS-compatible digital outputs. It delivers 7.3 effective bits 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 ADC08200CIMTX/NOPB datasheet, ADC08200CIMTX/NOPB pinout, ADC08200CIMTX/NOPB application, or ADC08200CIMTX/NOPB equivalent, key selection considerations include its 200 Msps sampling rate, 7.3-bit ENOB at 50 MHz, ±0.4 LSB typical DNL, power-down mode (1 mW), and straight-binary output format compatible with 2.5V/3V logic interfaces.

Technical Context

The ADC08200CIMTX/NOPB employs a unique switched-capacitor pipeline architecture with integrated track-and-hold, achieving 7.3 effective bits up to 100 MHz input while maintaining ±0.4 LSB typical DNL and −60 dBc THD at 50 MHz. Its reference ladder features accessible VRT, VRM, and VRB pins for flexible input range configuration between 0.3 V and 1.9 V.

Digital timing is synchronized to the rising edge of CLK, with 6-clock-cycle pipeline latency and output delay under 5.1 ns. Power consumption scales linearly at 1.05 mW/Msps, and the PD pin enables low-power state where outputs hold last valid data and total dissipation drops to 1 mW with CLK held low.

FAQ

What is the maximum guaranteed sampling rate for ADC08200CIMTX/NOPB?

The ADC08200CIMTX/NOPB has a minimum guaranteed maximum conversion rate of 200 Msps under specified operating conditions (VA = VDR = +3.0 V, TJ = −40°C to +105°C). The datasheet notes performance up to 230 Msps is achievable but not production-tested; design margin should be based on the 200 Msps limit. This rate enables Nyquist sampling of signals up to 100 MHz.

Does ADC08200CIMTX/NOPB require an external sample-and-hold circuit?

No, ADC08200CIMTX/NOPB integrates a track-and-hold function on-chip. The internal sample-and-hold eliminates the need for external components, reducing PCB area, signal path complexity, and timing skew. Input acquisition occurs on the rising edge of CLK, and the hold phase begins immediately thereafter - confirmed in the Functional Description and Timing Diagram sections of the SNAS136M datasheet.

What is the power consumption of ADC08200CIMTX/NOPB in power-down mode?

In power-down mode (PD = high), ADC08200CIMTX/NOPB consumes 1 mW typical when the CLK input is held low. With CLK active, power rises to 1.4 mW typical. This ultra-low standby power is enabled by shutting down internal bias circuits while retaining output latch state - allowing rapid wake-up without reinitialization. Total current draw drops to ~0.3 mA under these conditions.

Can ADC08200CIMTX/NOPB interface directly with 2.5V logic systems?

Yes, ADC08200CIMTX/NOPB supports direct 2.5V logic interfacing via its dedicated VDR pin. When VDR is supplied at 2.5V (within 2.4 V to VA range), the D0–D7 outputs meet TTL/CMOS voltage thresholds for VOH ≥ 2.0 V and VOL ≤ 0.4 V, eliminating level shifters. This is explicitly validated in the Digital Output Characteristics table (page 6) of the SNAS136M datasheet.

What is the effective number of bits (ENOB) of ADC08200CIMTX/NOPB at 100 MHz input frequency?

At fIN = 100 MHz, the ADC08200CIMTX/NOPB achieves 7.0 bits typical ENOB, as specified in the Dynamic Performance table (page 6) of SNAS136M. This corresponds to ~44 dB SINAD and reflects maintained signal fidelity under high-frequency full-scale input conditions - critical for undersampling and IF digitization applications.
