Texas Instruments THS1207CDAR

Overview

THS1207CDAR from Texas Instruments is a 12-bit, 6 MSPS pipelined analog-to-digital converter (ADC) with simultaneous sampling across four analog inputs. It supports single-ended or differential configurations (up to two differential channels), features internal 1.5 V/3.5 V references (±5% accuracy, 50 ppm/°C), and operates on a single 5-V analog supply. Its 68 dB SNR at 2 MHz and glueless DSP interface make it suitable for radar front-ends and high-speed communications receivers.

For engineers reviewing the THS1207CDAR datasheet, THS1207CDAR pinout, THS1207CDAR application, or THS1207CDAR equivalent, key selection criteria include simultaneous 4-channel sampling capability, 5-V analog/3.3-V digital supply separation, programmable auto-scan mode, and SYNC-driven multichannel data alignment - all critical for time-coherent acquisition in DSP-based signal processing systems.

Technical Context

The THS1207CDAR implements a multistage pipelined ADC architecture with output error correction logic, ensuring no missing codes over 0°C to 70°C. Its 5-cycle pipeline latency enables deterministic timing for real-time synchronization via the dedicated SYNC output.

It supports flexible input configuration through internal control registers (CR0/CR1), allowing runtime selection of channel count (1–4), differential/single-ended mode, reference source (internal or external), and power-down state - all accessed via parallel D0–D11 bus with RA0/RA1 address lines.

FAQ

What is the operating temperature range for the THS1207CDAR?

The THS1207CDAR is characterized for operation from 0°C to 70°C ambient temperature (commercial grade). This range is specified in the ordering information as THS1207CDA, and the 'C' suffix confirms the 0°C to 70°C rating. The device uses a TSSOP-32 (DA) package and meets all electrical specifications within this temperature window.

Does the THS1207CDAR support external reference voltage sources?

Yes, the THS1207CDAR supports external references via REFP and REFM pins. When bit VREF in Control Register 0 is set to 1, the internal reference is disabled and the external 2-V span (REFP – REFM) becomes active. The device retains full specification compliance with external references meeting the recommended 1.4 V to 3.7 V range and stability requirements.

How does the SYNC output function in multichannel mode for the THS1207CDAR?

In multichannel mode, the THS1207CDAR asserts SYNC low when channel-A data is valid on the D0–D11 bus. Its timing is deterministic: latency equals 5 pipeline cycles plus the number of sampled channels (e.g., 7 cycles for 2-channel mode). This enables precise FPGA or DSP synchronization without additional clock domain crossing logic.

Can the THS1207CDAR operate with mixed single-ended and differential inputs simultaneously?

Yes, the THS1207CDAR supports hybrid configurations - for example, one differential pair (AINP/AINM) and one single-ended input (BINP referenced to REFIN). Channel selection and input mode are independently programmed per channel via DIFF0/DIFF1 and CHSEL0/CHSEL1 bits in Control Register 0, enabling flexible sensor interface mapping.

What is the power-down current consumption of the THS1207CDAR?

The THS1207CDAR draws ≤1 mW in power-down mode with the conversion clock inactive, corresponding to approximately 200 µA total supply current at 5 V. Power-down is enabled by setting bit PD in Control Register 0, and the device retains register contents and resumes conversion within microseconds upon exit.
