Texas Instruments THS1007IDA

Overview

THS1007IDA from Texas Instruments is a 10-bit, 6-MSPS simultaneous-sampling analog-to-digital converter with four analog inputs, internal 5-V analog supply operation, ±1 LSB integral nonlinearity, and 59 dB SINAD at 2 MHz - deployed in radar front-ends requiring synchronized multi-channel acquisition.

For engineers reviewing the THS1007IDA datasheet, THS1007IDA pinout, THS1007IDA application, or THS1007IDA equivalent, this page delivers verified electrical specs, TSSOP-32 package mapping, differential/single-ended input configuration logic, and real-world timing behavior for multichannel DSP interfacing.

Technical Context

The THS1007IDA implements a multistage pipelined ADC architecture with output error correction logic to guarantee no missing codes across −40°C to +85°C. It supports simultaneous sampling of up to four single-ended or two differential inputs, with programmable auto-scan mode for 2–4 channels.

Conversion is clocked externally via CONV_CLK (up to 6 MHz), with fixed 5-cycle pipeline latency and SYNC-driven channel synchronization. Internal reference voltages (1.5 V / 3.5 V) are provided, and external reference selection is supported via REFP/REFM pins with register-controlled configuration.

Key Specifications

Pinout & Package

TSSOP-32 package (DA suffix), 0.65 mm pitch, 7.0 mm × 4.4 mm body size, exposed thermal pad optional - compatible with standard surface-mount reflow profiles and automated optical inspection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-speed simultaneous-sampling ADC applications.

Compared with ADS8556IPMR and AD7606BSTZ, the THS1007IDA uniquely delivers 10-bit resolution at 6 MSPS with true 4-channel simultaneous sampling and sub-100 ps inter-channel skew - making it irreplaceable in coherent RF and high-speed control loops where timing alignment dominates resolution requirements.

FAQ

What is the guaranteed operating temperature range for THS1007IDA?

The THS1007IDA is characterized for operation from −40°C to +85°C, meeting industrial and automotive environmental requirements. This rating is explicitly defined in the ordering information section of the datasheet and confirmed by thermal testing under recommended operating conditions including AVDD = DVDD = 5 V and BVDD = 3.3 V.

Does THS1007IDA support differential input mode on all four analog channels?

No - THS1007IDA supports up to two differential input pairs (AINP/AINM and BINP/BINM), corresponding to Channels A and B. The remaining two inputs (C and D) are configurable only as single-ended in hardware; differential operation is not supported for those channels per the functional block diagram and terminal descriptions.

What is the latency of THS1007IDA and how does it affect system timing?

The THS1007IDA has a fixed 5-cycle pipeline latency from CONV_CLK falling edge to valid D0–D9 output. This value is specified in the timing requirements table and verified in Figures 28–31. System-level timing must account for this delay when aligning SYNC pulses and read strobes - especially in multichannel configurations where SYNC timing shifts with channel count.

Can THS1007IDA operate with a 3.3-V digital interface while using 5-V analog supplies?

Yes - THS1007IDA supports independent supply rails: AVDD = 5 V for analog circuitry, DVDD = 3.3 V or 5 V for digital I/O, and BVDD = 3.3 V for output buffers. The datasheet specifies VIH/VIL thresholds for both 3.3 V and 5.25 V DVDD conditions, enabling direct interfacing with 3.3-V microcontrollers without level shifters.

How is the internal reference configured and what are its accuracy limits?

The THS1007IDA uses internal 1.5 V (REFM) and 3.5 V (REFP) references by default, with ±5% initial accuracy and 50 ppm/°C temperature coefficient. These values are measured under AVDD = 5 V, f_s = 6 MSPS, and are documented in the Electrical Characteristics tables - no external configuration is needed unless switching to an external reference via control register bit VREF.
