Texas Instruments THS1030IDWR

Overview

THS1030IDWR from Texas Instruments is a 10-bit, 30 MSPS analog-to-digital converter (ADC) with configurable single-ended or differential 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 and features an out-of-range indicator and power-down mode - used in CCD-based imaging systems including digital cameras and camcorders.

For engineers reviewing the THS1030IDWR datasheet, THS1030IDWR pinout, THS1030IDWR application, or THS1030IDWR equivalent, key selection considerations include its TSSOP-28 package, −40°C to 85°C industrial temperature range, 30 MSPS sampling rate with pipeline latency of 3 cycles, and flexible reference configuration via MODE/REFSENSE/VREF pins.

Technical Context

The THS1030IDWR implements a CMOS pipeline ADC architecture with sample-and-hold front-end, internal reference buffer, and digital output buffers controlled by OE. Its MODE pin selects among three reference generation modes: full external (MODE = AGND), differential (MODE = AVDD/2), or top/bottom (MODE = AVDD), each defining distinct REFTF/REFBF sourcing and input topology.

Reference configuration directly determines input span: in top/bottom mode, REFTS and REFBS set FS+ and FS−; in differential mode, VREF defines REFTF–REFBF difference while REFTS/REFBS serve as AIN−; in external mode, REFTF/REFBF are driven directly with Kelvin sense capability. Aperture jitter is specified at 2 ps, supporting high-fidelity acquisition up to 150 MHz full-power bandwidth.

Key Specifications

Pinout & Package

THS1030IDWR is housed in a 28-pin TSSOP (Thin Shrink Small Outline Package) with 0.65 mm lead pitch, JEDEC MO-153 compliant, and rated for −40°C to +85°C operation. The package supports fine-pitch PCB layout and thermal performance suitable for high-speed ADC placement near analog front-ends.

FAQ

What is the maximum sampling rate supported by the THS1030IDWR?

The THS1030IDWR supports a maximum sampling rate of 30 MSPS, verified across its full −40°C to +85°C operating temperature range. This rate is sustained with guaranteed AC performance including 57 dB SNR and 60 dB SFDR at 3.5 MHz input frequency. Clock timing requires minimum high/low pulse widths of 15 ns and cycle time of 33 ns, corresponding to a 30.3 MHz upper limit.

Does the THS1030IDWR support differential input configurations?

Yes, the THS1030IDWR supports true differential input operation when MODE is tied to AVDD/2. In this mode, REFTS and REFBS serve as the complementary AIN− path, while AIN is the AIN+ path; the internal reference buffer generates REFTF and REFBF centered at AVDD/2 with spacing equal to the VREF voltage. This configuration is explicitly validated in the datasheet Figures 15–17 and enables rejection of common-mode noise in sensor interfaces.

What reference voltage options are available on the THS1030IDWR?

The THS1030IDWR provides three reference architectures: full external (MODE = AGND), differential (MODE = AVDD/2), and top/bottom (MODE = AVDD). Internally, it generates 1 V or 2 V references selectable via REFSENSE pin connection. VREF serves as both input (for external reference) and output (for internal generator), and REFTS/REFBS can be used as sense lines in Kelvin configuration to eliminate PCB trace resistance errors.

Is the THS1030IDWR pin-compatible with other devices?

Yes, the THS1030IDWR is pin-compatible with the TLC876 as stated in the datasheet description. Both share identical pin functions and TSSOP-28/SOIC-28 footprints. However, functional differences exist: TLC876 is an 8-bit device with different timing and reference behavior, so direct substitution requires validation of resolution, SNR, and mode configuration compatibility in the target application.

What is the purpose of the OVR pin on the THS1030IDWR?

The OVR (Out-of-Range) pin on the THS1030IDWR is an open-drain output that asserts high when the analog input voltage at AIN exceeds the upper threshold (REFTS) or falls below the lower threshold (REFBS) in top/bottom mode. It provides real-time hardware-level detection of signal clipping or sensor saturation, enabling immediate system response such as gain adjustment or alarm triggering without CPU intervention.
