Texas Instruments ADC10D040CIVS/NOPB

Overview

ADC10D040CIVS/NOPB from Texas Instruments is a dual-channel, 10-bit, 40 MSPS analog-to-digital converter with internal sample-and-hold, internal reference capability, and selectable offset binary or 2's complement output coding. It operates from a single 3.3 V supply, consumes 267 mW typical, and delivers 9.4 ENOB over the full Nyquist band - used in CCD imaging, ultrasound systems, and portable instrumentation where low power and high-speed dual-channel sampling are required.

For engineers reviewing the ADC10D040CIVS/NOPB datasheet, ADC10D040CIVS/NOPB pinout, ADC10D040CIVS/NOPB application, or ADC10D040CIVS/NOPB equivalent, key selection considerations include its dual 10-bit parallel/multiplexed output bus, 2.5–3.0 clock-cycle latency, ±10 ps aperture jitter, 140 MHz full-power bandwidth, and support for independent I/Q channel offset correction.

Technical Context

The ADC10D040CIVS/NOPB employs a two-stage pipelined architecture enabling 9.4 effective bits at 40 MSPS while maintaining no missing codes across −40°C to +85°C. Its dual independent ADC cores digitize differential analog inputs (I+/I− and Q+/Q−) with programmable gain (×1 or ×2 relative to VREF), internal reference (0.6–1.6 V), and common-mode output (VCMO = 1.5 V).

Digital interface flexibility includes OS-pin-selectable 10-bit multiplexed or 20-bit parallel outputs, OF-pin-configurable offset binary/2's complement coding, and separate VDR supply (1.5–3.6 V) for TTL-compatible output drivers. Power management features include <1 mW power-down mode (recovery <1 ms) and 30 mW standby mode (recovery 800 ns).

Key Specifications

Pinout & Package

The ADC10D040CIVS/NOPB is housed in a 48-pin TQFP (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad. Analog, digital, and driver ground pins are physically separated and require local star-point connection near the package per datasheet layout guidance.

FAQ

What is the guaranteed operating temperature range for the ADC10D040CIVS/NOPB?

The ADC10D040CIVS/NOPB is specified for continuous operation across the industrial temperature range of −40°C to +85°C. All key specifications-including ENOB, DNL, and power consumption-are ensured across this full range. The device uses a CMOS process optimized for thermal stability, and its internal reference and offset correction maintain accuracy without external calibration over temperature.

Does the ADC10D040CIVS/NOPB support true simultaneous sampling of both I and Q channels?

Yes, the ADC10D040CIVS/NOPB implements two fully independent ADC cores with separate analog front-ends (I+/I− and Q+/Q−), enabling true simultaneous sampling on the same CLK falling edge. Channel-to-channel aperture delay match is 8.5 ps, and gain matching is within 0.1% FS - critical for coherent I/Q signal processing in zero-IF receivers and ultrasound beamformers.

How does the offset correction feature work in the ADC10D040CIVS/NOPB?

The ADC10D040CIVS/NOPB performs per-channel offset correction via the OC pin: a low-to-high transition triggers a 34-clock-cycle sequence during which 32 conversions are averaged and subtracted from subsequent results. This reduces offset error from ±1.2 LSB to ±0.5 LSB. Both I and Q channels correct independently, and the input differential voltage must remain at 0 V throughout the entire correction period.

Can the ADC10D040CIVS/NOPB operate with a 2.5 V digital output supply (VDR)?

Yes, the ADC10D040CIVS/NOPB supports VDR from +1.5 V to VD (max +3.6 V). At VDR = +2.5 V, VOH is guaranteed ≥2.3 V and VOL ≤0.4 V under load, ensuring compatibility with 2.5 V LVTTL and mixed-voltage FPGA interfaces. Output drive strength scales with VDR, and the datasheet specifies short-circuit currents accordingly.

What is the minimum clock duty cycle supported by the ADC10D040CIVS/NOPB?

The ADC10D040CIVS/NOPB requires a clock duty cycle between 45% and 55% for guaranteed operation at 40 MSPS. Outside this range, aperture jitter increases and ENOB degrades - particularly above 10 MHz input frequencies. The datasheet specifies 50% nominal, and timing diagrams show setup/hold margins optimized for symmetric edges.
