Texas Instruments ADC08060CIMTX/NOPB

Overview

ADC08060CIMTX/NOPB from Texas Instruments is an 8-bit, single-ended analog-to-digital converter with internal sample-and-hold, operating at 20–60 MSPS with 7.5 ENOB at 25 MHz input, −60 dB THD (typ), and 1.3 mW/MSPS power efficiency. It functions as a high-speed front-end digitizer in imaging and communications signal chains, supporting TTL/CMOS-compatible digital outputs and 3V single-supply operation.

For engineers reviewing the ADC08060CIMTX/NOPB datasheet, ADC08060CIMTX/NOPB pinout, ADC08060CIMTX/NOPB application, or ADC08060CIMTX/NOPB equivalent, key selection considerations include its 24-pin TSSOP package, 60 MSPS maximum sampling rate, 7.5-bit effective resolution at RF input frequencies, power-down mode (1 mW), and reference ladder architecture enabling flexible VIN range definition via VRT/VRB pins.

Technical Context

The ADC08060CIMTX/NOPB employs a unique switched-capacitor bandgap architecture that delivers stable 7.4–7.6 ENOB across 4.4–29 MHz input frequencies while maintaining 1.3 mW/MSPS power scaling. Its pipeline latency is fixed at 2.5 clock cycles plus 8.2 ns output delay, with aperture jitter of 2 ps rms enabling clean spectral performance up to 25 MHz.

It uses a monolithic 8-bit flash-plus-encoder structure with coarse/fine comparators and error correction, supported by an on-chip track-and-hold. The reference ladder (VRT–VRB) defines the full-scale range, with VRM providing midpoint access for biasing; all analog inputs require bypassing per TI's layout guidelines to maintain SNR >46 dB.

FAQ

What is the maximum sampling rate guaranteed for ADC08060CIMTX/NOPB?

The ADC08060CIMTX/NOPB is specified with a minimum maximum sampling rate of 60 MSPS across the industrial temperature range (−40°C to +85°C). At room temperature, it operates up to 70 MSPS, but system designs must rely on the 60 MSPS guaranteed limit for timing-critical applications. This rate supports Nyquist bandwidths up to 30 MHz and is validated with 50% duty-cycle CLK input meeting tCL/tCH ≥6.7 ns.

Does ADC08060CIMTX/NOPB require an external sample-and-hold circuit?

No, ADC08060CIMTX/NOPB integrates a fully functional sample-and-hold circuit optimized for its architecture. The device samples the analog input on the falling edge of CLK and holds the value internally-eliminating the need for external S/H components. This simplifies board layout and reduces acquisition time uncertainty, especially when paired with fast amplifiers like the LMH6702.

How does the power-down mode affect ADC08060CIMTX/NOPB output behavior?

When the PD pin is driven high, ADC08060CIMTX/NOPB enters power-down mode, reducing total supply current to 1 mW (typical) and halting internal conversion. Critically, the digital output pins (D0–D7) retain their last valid conversion result and remain in a high-impedance state only if externally pulled-no bus contention occurs, enabling seamless wake-up without re-synchronization.

Can ADC08060CIMTX/NOPB interface directly with 2.5V logic systems?

Yes, ADC08060CIMTX/NOPB supports direct 2.5V logic interfacing via its dedicated DR VD pin (pin 18), which powers the output drivers independently of the +3V analog supply VA. When DR VD is set to 2.5V and properly decoupled, the D0–D7 outputs meet 2.5V TTL/CMOS voltage thresholds (VOH ≥2.0V, VOL ≤0.4V), eliminating level-shifters in mixed-voltage systems.

What reference configuration is required to achieve the published ENOB of 7.5 bits?

To achieve the 7.5-bit ENOB at 25 MHz input, ADC08060CIMTX/NOPB requires a low-noise, low-impedance reference setup: VRT = 1.9V and VRB = 0.3V (1.6V span), with VRM (pin 9) bypassed to AGND using a 0.1 µF capacitor. External reference drivers must source/sink ≥7.3 mA to maintain ladder stability; deviations in VRT–VRB or poor bypassing degrade ENOB below specification.
