Product details
Overview
THS1030CPW from Texas Instruments is a 10-bit, 30 MSPS CMOS analog-to-digital converter (ADC) with configurable single-ended or differential analog input, ±0.3 LSB differential nonlinearity, 57 dB signal-to-noise ratio, and adjustable internal voltage reference. It operates from 3 V to 5.5 V supply and delivers high-speed digitization for CCD-based imaging systems such as digital cameras and camcorders.
For engineers reviewing the THS1030CPW datasheet, THS1030CPW pinout, THS1030CPW application, or THS1030CPW equivalent, key selection considerations include its TSSOP-28 package, 0°C to 70°C temperature rating, out-of-range indicator (OVR), power-down mode, and pin compatibility with TLC876 in shared system designs.
Technical Context
The THS1030CPW implements a switched-capacitor sample-and-hold front-end feeding a 10-bit flash/successive-approximation hybrid ADC core, with pipeline latency of 3 clock cycles and aperture jitter of 2 ps. Its reference architecture supports three distinct modes-full external, differential, and top/bottom-selected via the MODE pin voltage (AGND, AVDD/2, or AVDD).
Reference generation is flexible: internal 1 V or 2 V references are selectable via REFSENSE connection, while REFTS/REFBS define input span boundaries in top/bottom mode, and VREF directly sets REFTF–REFBF differential range in differential mode. The OVR output asserts high on input violation beyond (REFTS, REFBS) bounds.
Key Specifications

Pinout & Package
TSSOP-28 (PW) package: 4.4 mm × 9.7 mm body, 0.65 mm pitch, thermally enhanced with exposed pad (not electrically connected per datasheet), rated for surface-mount reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AIN (27) | Analog input | Primary analog signal node; accepts single-ended or differential input depending on MODE and REFTS/REFBS configuration. |
| CLK (15) | Sample-rate clock input | Rising-edge-triggered; 33 ns minimum cycle time supports up to 30 MSPS sampling with 3-cycle pipeline latency. |
| I/O0–I/O9 (3–12) | Parallel digital output bus | 10-bit CMOS-compatible data bus (LSB to MSB); tri-stated when OE is high, enabling shared bus interfacing. |
| OVR (13) | Out-of-range indicator | Active-high flag signaling AIN violation beyond REFTS/REFBS window; synchronized to data output timing. |
| MODE (23) | Reference architecture selector | Configures ADC reference generation: AGND = external reference, AVDD/2 = differential mode, AVDD = top/bottom mode. |
| OE (16) | Output enable | Controls digital bus drive state: low = enabled, high = high-impedance - essential for multi-device data bus sharing. |
| STBY (17) | Power-down control | High = standby mode; reduces current draw to 3–5 mA, enabling rapid wake-up without full re-initialization. |
| REFSENSE (18) | Onboard reference generator control | Selects internal VREF: AGND → 2 V, VREF pin → 1 V, external divider → programmable, AVDD → disabled. |
| REFTS / REFBS (21, 25) | Top/bottom reference sense inputs | In top/bottom mode, define analog input span endpoints; in differential mode, serve as AIN− complementary input pair. |
| VREF (26) | Internal/external reference I/O | Serves as reference source (1 V or 2 V) when REFSENSE configured accordingly; or accepts external reference voltage. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable input topology | Single-ended or differential operation via MODE and REFTS/REFBS wiring - eliminates need for external op-amp front-end in many CCD interfaces. |
| Three-reference-generation modes | Full external (MODE = AGND), differential (MODE = AVDD/2), top/bottom (MODE = AVDD) - enables optimal SNR and layout flexibility per application. |
| Adjustable internal voltage reference | 1 V or 2 V selectable via REFSENSE; supports Kelvin-connected external references to eliminate PCB trace IR drop errors. |
| Out-of-range detection | Dedicated OVR pin provides immediate hardware-level alert on input overvoltage/undervoltage - simplifies system fault handling without software polling. |
| Low-power standby mode | Reduces supply current to ≤5 mA while retaining configuration state - ideal for burst-mode acquisition in portable imaging devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog-to-digital conversion applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC876IPW | Pin-compatible 10-bit, 25 MSPS ADC; lower max sampling rate, no MODE-selectable reference modes, fixed internal reference only. | Limited to single-ended input and fixed 2.5 V reference; unsuitable for differential CCD inputs or custom span adjustment. | Choose TLC876IPW only if design uses legacy TLC876 layout and requires no reference flexibility or 30 MSPS performance. |
| ADS8320E | 16-bit, 1 MSPS SAR ADC; higher resolution but 30× slower; SPI interface vs. parallel; no OVR or MODE pin. | Targeted at precision measurement, not high-speed imaging; lacks real-time out-of-range monitoring and fast parallel throughput. | Select ADS8320E only for low-speed, high-accuracy applications where resolution outweighs speed and interface requirements. |
Compared with TLC876IPW and ADS8320E, the THS1030CPW uniquely balances 30 MSPS speed, 10-bit linearity, configurable input topology, and hardware OVR signaling - making it the only option among the three suitable for real-time CCD digitization with adaptive reference control.

FAQ
What is the maximum sampling rate supported by the THS1030CPW?
The THS1030CPW supports a maximum sampling rate of 30 MSPS, verified under recommended operating conditions (AVDD = DVDD = 3 V to 5.5 V, 50% duty cycle clock). At this rate, it achieves 57 dB SNR and 60 dB SFDR at 3.5 MHz input frequency. Performance degrades gradually above 30 MSPS due to aperture jitter and pipeline timing limits - operation beyond this rate is not characterized or guaranteed in the THS1030CPW datasheet.
How does the MODE pin affect THS1030CPW reference configuration?
The MODE pin on the THS1030CPW selects one of three reference architectures: AGND enables full external reference mode (REFTF/REFBF driven externally), AVDD/2 enables differential mode (VREF defines REFTF–REFBF span), and AVDD enables top/bottom mode (REFTS/REFBS set input span endpoints). Each mode changes internal switch states and buffer routing - incorrect MODE voltage causes undefined reference behavior and conversion errors in the THS1030CPW.
Does the THS1030CPW support differential analog input?
Yes, the THS1030CPW supports true differential analog input when configured in MODE = AVDD/2. In this mode, AIN serves as the positive input and the REFTS/REFBS pair functions as the complementary negative input to the sample-and-hold stage. This configuration enables common-mode rejection and improved noise immunity for CCD and video signal paths - confirmed in Figures 15–17 of the THS1030CPW datasheet.
What is the purpose of the OVR pin on the THS1030CPW?
The OVR (Out-of-Range) pin on the THS1030CPW is an active-high, synchronous indicator that asserts when the analog input voltage at AIN exceeds the valid conversion window defined by REFTS and REFBS. It outputs concurrent with the corresponding digital code, enabling real-time hardware fault detection without CPU intervention - a critical feature for protecting downstream image processing logic in THS1030CPW-based scanners and cameras.
Can the THS1030CPW operate from a single 3.3 V supply?
Yes, the THS1030CPW is fully specified to operate from a single 3.3 V supply (AVDD = DVDD = 3.3 V), with typical power dissipation of 87–120 mW at 30 MSPS. All electrical characteristics - including 57 dB SNR, ±0.3 LSB DNL, and 33 ns clock period - are validated at 3 V min and 3.3 V nominal. The device maintains full functionality across the 3 V to 5.5 V range without configuration changes, making it compatible with modern low-voltage imaging subsystems using the THS1030CPW.
