Product details
Overview
ADC08100CIMTCX/NOPB from Texas Instruments is an 8-bit, single-ended analog-to-digital converter with on-chip track-and-hold, operating at 20–100 Msps sampling rates, consuming 1.3 mW/Msps (130 mW at 100 Msps), and featuring TTL/CMOS-compatible digital outputs powered by a separate DR VD supply. It delivers 7.4 ENOB at 41 MHz input frequency and supports industrial temperature range (−40°C to +85°C) in a 24-pin TSSOP package.
For engineers reviewing the ADC08100CIMTCX/NOPB datasheet, ADC08100CIMTCX/NOPB pinout, ADC08100CIMTCX/NOPB application, or ADC08100CIMTCX/NOPB equivalent, key selection considerations include its 100 Msps maximum sampling rate, 1.3 mW/Msps power efficiency, straight-binary output format, single +3V analog supply (VA), and independent output driver supply (DR VD) supporting 2.5V/3V logic interfacing.
Technical Context
The ADC08100CIMTCX/NOPB employs a unique switched-capacitor bandgap architecture enabling 7.4 effective bits at 41 MHz input while maintaining low power proportional to clock frequency. Its sampling occurs on the falling edge of CLK, with pipeline latency of 2.5 clock cycles plus 5.9 ns output delay (tOD), and aperture jitter of just 2 ps rms.
It integrates internal sample-and-hold, supports programmable reference configuration via VRT (top), VRB (bottom), and VRM (midpoint) pins, and features a dedicated Power Down (PD) input that reduces consumption to 1 mW while holding last valid output. Digital I/Os are TTL/CMOS compatible with separate VA (analog) and DR VD (driver) supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 8 bits - guarantees monotonic operation with no missing codes across full industrial temperature range. |
| Max Sampling Rate | 100 Msps (min) - enables digitization of signals up to Nyquist frequency of 50 MHz with guaranteed timing margins. |
| ENOB @ 41 MHz | 7.4 bits (typ) - reflects actual usable resolution under high-frequency AC conditions, critical for imaging and comms signal fidelity. |
| Power Efficiency | 1.3 mW/Msps (typ) - scales linearly with clock rate, delivering 130 mW at 100 Msps and only 1 mW in PD mode. |
| Aperture Jitter | 2 ps rms - directly limits SNR degradation at high input frequencies; enables >46 dB SNR at 41 MHz. |
| Reference Flexibility | VRT/VRB programmable (1.0V–2.3V delta) - allows user-defined full-scale range from 0.3V to 1.9V, supporting diverse sensor and video signal levels. |
| Digital Interface | TTL/CMOS-compatible D0–D7 outputs with separate DR VD supply - permits direct interfacing to 2.5V or 3V logic without level shifters. |
Pinout & Package
ADC08100CIMTCX/NOPB is housed in a 24-lead TSSOP (Thin Shrink Small Outline Package) with exposed thermal pad (not electrically connected), optimized for high-density PCB layouts and thermal performance in portable and imaging systems.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Analog input | Single-ended signal input referenced to VRB–VRT range; 3–4 pF input capacitance (clock-dependent); requires low-output-impedance driver (e.g., LMH6702). |
| VRT / VRB / VRM | Reference ladder terminals | Top/mid/bottom nodes of internal resistor ladder; define conversion range and enable precision external biasing; VRM must be bypassed with 0.1 µF to clean AGND. |
| CLK | Digital clock input | Falling-edge-triggered sampling control; min 4.5 ns high/low pulse width; supports 20–100 MHz operation with 50% duty cycle. |
| PD | Power-down control | Active-high logic input; places device in 1 mW standby while freezing D0–D7 outputs at last valid conversion result. |
| D0–D7 | Digital data outputs | Straight-binary 8-bit parallel outputs; valid after tOD = 5.9 ns (max) from CLK rise; driven by DR VD supply (2.4V–VA). |
| VA / DR VD / AGND / DR GND | Power & ground rails | VA (+2.7V to +3.6V) powers analog core; DR VD (+2.4V to VA) powers outputs; separate AGND/DR GND grounds reduce noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Frequency-scaled power consumption | 1.3 mW/Msps ensures minimal thermal load and battery drain in portable instruments - power drops linearly with reduced sampling rate. |
| Independent output driver supply | DR VD pin allows direct interface to 2.5V FPGA I/O banks or 3V microcontrollers without level-shifting circuitry or voltage translation ICs. |
| Programmable reference architecture | VRT/VRB/VRM pins enable precise full-scale adjustment (e.g., 0.3V–1.9V range) and support external low-impedance reference drivers for <±0.5 LSB INL. |
| Low-aperture-jitter sampling | 2 ps rms aperture jitter preserves dynamic performance up to 41 MHz input - essential for medical scan converters and astronomy CCD readout. |
| Robust digital I/O | TTL/CMOS-compatible inputs (CLK, PD) and outputs (D0–D7) tolerate −0.3V to VA+0.3V; outputs short-circuit protected per TI specification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-bit, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADC08080CIMTX/NOPB | Lower max sampling rate (80 Msps vs. 100 Msps); identical 8-bit resolution, 1.3 mW/Msps efficiency, and TSSOP-24 package. | Not suitable for 100 Msps systems (e.g., high-end set-top boxes or fast-scan medical imaging); otherwise pin- and function-compatible. | Select ADC08080CIMTX/NOPB only when system clock is ≤80 MHz and cost optimization is prioritized over peak throughput. |
| ADS830E | 8-bit, 60 Msps max; higher power (25 mW/Msps); different 20-pin SOIC package; no separate DR VD supply - outputs fixed to VA. | Lacks flexible logic interfacing capability; unsuitable for mixed-voltage systems; lower SFDR (54 dBc) limits RF/comms use. | Choose ADS830E only for legacy designs with space-constrained SOIC footprints and no requirement for 2.5V logic compatibility or >60 Msps operation. |
Compared with ADC08100CIMTCX/NOPB, ADC08080CIMTX/NOPB offers identical architecture and efficiency but sacrifices 20 Msps headroom, while ADS830E trades power efficiency, interface flexibility, and dynamic performance for smaller footprint - making ADC08100CIMTCX/NOPB optimal for new designs demanding full 100 Msps capability with 2.5V/3V interoperability.

FAQ
What is the maximum sampling rate supported by ADC08100CIMTCX/NOPB?
The ADC08100CIMTCX/NOPB supports a guaranteed minimum sampling rate of 100 Msps across its industrial temperature range (−40°C to +85°C), with typical operation up to 125 MHz under specific conditions. This enables digitization of signals with bandwidths up to 50 MHz while maintaining 7.4 ENOB and −60 dBc THD performance as specified in the SNAS060I datasheet.
Does ADC08100CIMTCX/NOPB require external reference components?
ADC08100CIMTCX/NOPB does not require external reference ICs but relies on externally applied voltages at VRT and VRB to define its conversion range. The device includes an internal resistor ladder; users may drive VRT/VRB directly with low-impedance sources (e.g., op-amp buffers) or use simple bias networks like those shown in Figure 30 of the datasheet. VRM must be bypassed with 0.1 µF to AGND.
How does the power-down mode affect ADC08100CIMTCX/NOPB output behavior?
When the PD pin is driven high, ADC08100CIMTCX/NOPB enters power-down mode, reducing current draw to 1 mW (typ) and freezing D0–D7 outputs at the last valid conversion result. Outputs remain TTL/CMOS-compatible and retain their logic state until PD returns low, enabling rapid wake-up without reinitialization or calibration.
Can ADC08100CIMTCX/NOPB interface directly with 2.5V logic devices?
Yes - ADC08100CIMTCX/NOPB supports direct 2.5V logic interfacing via its dedicated DR VD supply pin. When DR VD is set to 2.5V, the D0–D7 outputs meet 2.5V TTL/CMOS voltage thresholds (VOH ≥2.0V, VOL ≤0.4V), eliminating the need for external level shifters in mixed-voltage systems such as FPGA-based video processors.
What is the aperture jitter specification for ADC08100CIMTCX/NOPB, and why does it matter?
ADC08100CIMTCX/NOPB specifies 2 ps rms aperture jitter, a critical parameter that directly limits achievable SNR at high input frequencies. At 41 MHz, this jitter contributes less than 0.5 dB SNR degradation, enabling the device to maintain 46 dB SNR and 7.4 ENOB - essential for applications like medical imaging and spectrum analysis where signal integrity is non-negotiable.
