Product details
Overview
THS4032CDGNR from Texas Instruments is a dual-channel, ultra-low-noise (1.2nV/√Hz), high-speed voltage-feedback operational amplifier in an 8-pin HVSSOP package. It delivers 100MHz bandwidth at G = 2, 100V/μs slew rate, –90dBc THD at 1MHz (RL = 1kΩ), ±15V operation, and 200mA output drive - optimized for precision signal conditioning in high-resolution data acquisition and imaging front-ends.
For engineers reviewing the THS4032CDGNR datasheet, THS4032CDGNR pinout, THS4032CDGNR application, or THS4032CDGNR equivalent, key selection criteria include input voltage noise density, channel-to-channel crosstalk (–61dBc), thermal performance in HVSSOP (RθJA = 52.0°C/W), and dual-channel matching for differential or parallel-drive configurations.
Technical Context
The THS4032CDGNR employs a complementary bipolar 30V process enabling GHz fT transistors, delivering unity-gain stability with 120MHz bandwidth and 70ns settling time (0.1%). Its voltage-feedback architecture supports both single-supply (9–32V) and split-supply (±4.5V to ±16V) operation without mode switching.
It features fully independent dual channels with matched AC performance: identical small-signal bandwidth, slew rate, and distortion specs per channel, plus measured –61dBc channel-to-channel crosstalk at 1MHz - critical for multi-channel simultaneous sampling systems where inter-channel isolation directly impacts effective resolution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 100MHz at G = 2 (–3dB); enables baseband signal amplification up to 50MHz with ≤3dB gain error |
| Slew Rate | 100V/μs (±15V); supports full-scale 20Vpp step response in ≤200ns without slewing distortion |
| Voltage Noise | 1.2nV/√Hz (f > 10kHz); contributes < 0.5μV RMS integrated noise in 10MHz bandwidth, preserving SNR in 16-bit ADC drivers |
| THD | –90dBc at 1MHz, RL = 1kΩ; ensures < –85dBc system-level harmonic distortion when driving SAR ADCs like ADS8422 |
| Output Drive | 200mA (typical); sustains ±13.6V swing into 1kΩ load, supporting active filter stages and cable drivers |
| Supply Range | ±4.5V to ±16V dual or 9V–32V single; accommodates industrial ±12V and medical ±15V rails without level-shifting |
| Crosstalk | –61dBc (1MHz); limits inter-channel interference to < 0.1% of signal amplitude in dual-channel DAQ systems |
Pinout & Package
THS4032CDGNR uses the 8-pin HVSSOP (DGN) package (3.0mm × 4.9mm), featuring an exposed thermal pad for enhanced heat dissipation (RθJB = 24.5°C/W). The package is RoHS-compliant and optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Low-impedance buffered output capable of sourcing/sinking 200mA; requires series resistor for >10pF capacitive loads |
| 1IN– | Channel 1 inverting input | Differential input node; connects to feedback network for inverting gain configurations |
| 1IN+ | Channel 1 noninverting input | High-impedance input (2MΩ) with 1.5pF capacitance; used for noninverting buffers and active filters |
| VCC– | Negative supply rail | Reference for internal biasing; must be ≥ –16V and ≤ VCC+ – 33V |
| 2IN+ | Channel 2 noninverting input | Matched to 1IN+; enables synchronous dual-channel signal processing without inter-channel skew |
| 2IN– | Channel 2 inverting input | Matched to 1IN–; supports independent feedback networks per channel |
| 2OUT | Channel 2 output | Electrically isolated from 1OUT; measured crosstalk –61dBc ensures minimal signal coupling |
| VCC+ | Positive supply rail | Power input for both channels; thermal pad must connect to large copper plane for RθJB = 24.5°C/W |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4032IDGNR | Same silicon, extended temperature range (–40°C to +85°C) vs. CDGNR (0°C to +70°C); identical electrical specs | Required for automotive or outdoor industrial deployments where ambient exceeds 70°C | Select THS4032IDGNR when operating temperature exceeds 70°C; otherwise CDGNR offers cost advantage for commercial-grade systems |
| OPA2691IDGKR | Higher 320MHz bandwidth but higher 2.1nV/√Hz noise; 110V/μs slew rate; different pinout (8-pin VSSOP) | Better for RF IF amplification >100MHz; less suitable for low-noise DAQ due to 75% higher voltage noise | Choose OPA2691IDGKR only when bandwidth >100MHz is mandatory and noise budget allows ≥2nV/√Hz |
Compared with THS4032IDGNR, the THS4032CDGNR trades extended temperature rating for lower cost in commercial environments; versus OPA2691IDGKR, it prioritizes noise performance over raw bandwidth - making THS4032CDGNR optimal for precision wideband analog front-ends where SNR dominates speed requirements.

FAQ
What is the maximum recommended supply voltage for THS4032CDGNR?
The absolute maximum supply voltage for THS4032CDGNR is ±16V (32V total) in dual-supply mode or 32V in single-supply mode. Operation beyond this risks permanent damage. For reliable long-term use, TI specifies ±15V as the maximum recommended dual-supply voltage, ensuring junction temperature remains within safe limits under full output load conditions.
Does THS4032CDGNR support single-supply operation?
Yes, THS4032CDGNR supports true single-supply operation from 9V to 32V. Its input common-mode range extends to within 1.5V of the negative rail and output swings to within 1.2V of each rail (at ±15V), enabling rail-to-rail input/output functionality when biased appropriately. This allows direct interfacing with microcontrollers and ADCs operating on 3.3V or 5V logic levels using proper level-shifting networks.
What is the thermal pad connection requirement for THS4032CDGNR?
The exposed thermal pad on the THS4032CDGNR HVSSOP package must be soldered to a large copper plane for optimal thermal performance (RθJB = 24.5°C/W). TI permits connecting the pad to any potential between VCC+ and VCC–, including ground or either supply rail - but recommends grounding for lowest noise and EMI susceptibility. Failure to connect the pad degrades thermal resistance by >2×, risking thermal shutdown under sustained 200mA load.
How does THS4032CDGNR compare to THS4031 in terms of pin compatibility?
THS4032CDGNR and THS4031CDGNR share identical 8-pin HVSSOP (DGN) footprints and pin assignments for power (VCC+, VCC–), inputs (1IN+, 1IN–, 2IN+, 2IN–), and outputs (1OUT, 2OUT). However, THS4031 lacks pins 5 and 6 (2IN+, 2IN–) and instead has NC and NULL pins - making them not pin-compatible. Board designs must allocate separate layouts for single- vs. dual-channel variants despite identical package dimensions.
Can THS4032CDGNR drive a 150Ω load at full bandwidth?
Yes, THS4032CDGNR is characterized for RL = 150Ω with 100MHz bandwidth (G = 2), 100V/μs slew rate, and –72dBc THD at 1MHz. Its 200mA output current ensures ±12.9V swing into 150Ω at ±15V supplies. However, driving reactive loads >10pF requires a 20–75Ω series isolation resistor at the output to maintain phase margin and prevent oscillation - a design requirement explicitly documented in TI's application notes for this device.
