Product details
Overview
THS4524MDBTREP from Texas Instruments is a quad-channel, very low-power, fully differential operational amplifier with negative-rail input and rail-to-rail output. It delivers 145 MHz bandwidth, 490 V/μs slew rate, –140 dBc HD3 at 10 kHz, and 4.6 nV/√Hz input voltage noise, enabling high-fidelity signal conditioning in space-constrained, low-power data acquisition systems such as precision ADC driver stages for defense-grade SAR and ΔΣ converters.
For engineers reviewing the THS4524MDBTREP datasheet, THS4524MDBTREP pinout, THS4524MDBTREP application, or THS4524MDBTREP equivalent, key selection criteria include its extended temperature range (–55°C to 125°C), VOCM-controlled output common-mode voltage, power-down capability (20 μA typical), and TSSOP-38 package compatibility with high-density PCB layouts in aerospace and medical instrumentation.
Technical Context
The THS4524MDBTREP implements a fully differential architecture with independent VOCM inputs per channel, supporting dc-coupled interfacing to analog-to-digital converters. Its NRI (negative-rail input) and RRO (rail-to-rail output) topology allows seamless connection to single-ended, ground-referenced sources using only a +2.5 V to +5.5 V single supply.
Each channel features dedicated power-down control, open-loop gain of 119 dB, and output balance error of –57 dB below 2 MHz. The VOCM path operates with 23 MHz bandwidth and 55 V/μs slew rate, ensuring accurate common-mode regulation during fast transients without compromising differential signal integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 145 MHz small-signal (G = 1, VS = 5 V) - supports wideband sensor signal conditioning up to ~70 MHz Nyquist for 14-bit+ ADCs. |
| Slew Rate | 490 V/μs (rising, differential) - enables clean 2-VPP step response with 3.4 ns rise time and <1% overshoot. |
| HD3 @ 10 kHz | –140 dBc (1 VRMS, RL = 1 kΩ) - ensures ultra-low distortion in audio and precision measurement front-ends. |
| Input Voltage Noise | 4.6 nV/√Hz at 100 kHz - preserves SNR in low-amplitude, high-gain stages driving 24-bit ΔΣ ADCs. |
| Quiescent Current | 1.15 mA per channel (VS = 5 V) - allows four-channel operation under 5 mA total, critical for battery-powered telemetry. |
| Operating Temp | –55°C to 125°C - qualified for extended-life deployment in military avionics and downhole oilfield electronics. |
| VOCM Control Range | 0.8 V to 4.2 V (VS = 5 V) - permits precise alignment of output common-mode to ADC reference midpoints. |
Pinout & Package
TSSOP-38 (DBT) package: 38-pin thin shrink small-outline package with exposed thermal pad; 0.65 mm pitch; 12.5 mm × 6.1 mm footprint; JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PD1–PD4 | Channel power-down enable (active-low) | Individually disable each amplifier to reduce system quiescent current; logic-compatible with 0.7 V / 2.1 V thresholds. |
| VIN1+ to VIN4– | Differential input pairs (4 channels) | Negative-rail input range (down to VS–) enables direct coupling to transducer outputs referenced to ground or negative supplies. |
| VOCM1–VOCM4 | Output common-mode voltage control inputs | Analog-set reference for differential output midpoint; 0.99 V/V gain and ±12.5 mV offset ensure accurate DC coupling to ADC inputs. |
| VOUT1+ to VOUT4– | Differential output pairs (4 channels) | Rail-to-rail swing (0.115 V to 4.65 V on 5 V supply) maximizes dynamic range into 1-kΩ differential loads. |
| VS1+ to VS4+ | Positive supply pins (per channel) | Independent positive rails allow mixed-supply configurations; all VS– pins internally tied for shared negative return. |
| VS– | Common negative supply (12 pins) | Multiple VS– connections minimize ground bounce and improve PSRR (>62 dB) across wide frequency range. |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential architecture | Eliminates even-order harmonics and common-mode interference; enables true differential signaling without external baluns. |
| Negative-rail input (NRI) | Accepts input signals down to VS–, simplifying interface to sensors and DACs operating near ground potential. |
| Rail-to-rail output (RRO) | Delivers >95% of full supply swing, maximizing usable dynamic range into ADCs with internal reference buffers. |
| VOCM-controlled common-mode | Enables dc-coupled ADC driving with sub-10 mV offset drift over temperature, avoiding AC-coupling capacitors and associated low-frequency roll-off. |
| Quad-channel integration | Reduces board area by 75% vs discrete solutions; maintains channel-to-channel crosstalk < –125 dB at 10 kHz for multi-channel synchronized sampling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fully differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS4520IDRCT | Higher bandwidth (570 MHz), higher quiescent current (15.3 mA/ch), rail-to-rail output only (no NRI). | Better suited for RF sampling and wideband communications; not suitable for ground-referenced sensor interfaces. | Select THS4520IDRCT only when >200 MHz bandwidth is required and power budget allows >60 mA total. |
| THS4130IDR | 150 MHz bandwidth, 16 mA/ch, no VOCM control, no power-down, non-rail-to-rail output swing. | Lacks dc-coupling capability and channel shutdown; requires external common-mode biasing for ADC interfacing. | Choose THS4130IDR only if VOCM control and ultra-low power are not required, and layout space permits discrete bias networks. |
Compared with THS4524MDBTREP, THS4520IDRCT trades 14× higher power for 4× bandwidth, while THS4130IDR omits critical features for precision ADC driving-making THS4524MDBTREP uniquely balanced for low-power, dc-coupled, multi-channel data acquisition in harsh environments.

FAQ
What is the maximum supply voltage rating for THS4524MDBTREP?
The absolute maximum supply voltage for THS4524MDBTREP is 5.5 V (VS+ to VS–). Operating beyond this risks permanent damage. The device is specified for reliable operation from 2.5 V to 5.5 V, with optimal performance observed at 3.3 V and 5 V supplies per the SBOS609A datasheet. THS4524MDBTREP must never be subjected to reverse polarity or transient overvoltage events exceeding ±0.7 V beyond the supply rails on any pin.
Does THS4524MDBTREP support dc-coupled ADC driving?
Yes, THS4524MDBTREP supports true dc-coupled ADC driving via its VOCM input pins, which precisely control the output common-mode voltage with 0.99 V/V gain and ±12.5 mV offset (at 5 V supply). This eliminates the need for AC-coupling capacitors and external bias networks when interfacing with differential-input ADCs like the ADS1278, preserving low-frequency response and simplifying layout. THS4524MDBTREP's NRI and RRO architecture further enables seamless ground-referenced source connectivity.
How many independent amplifiers does THS4524MDBTREP contain?
THS4524MDBTREP contains four fully independent, fully differential operational amplifiers in a single TSSOP-38 package. Each channel has dedicated input (VINx+, VINx–), output (VOUTx+, VOUTx–), VOCM control (VOCMx), and power-down (PDx) terminals. The VS– pins are internally tied but provided at multiple locations to reduce ground impedance; VS+ pins are separated per channel to support flexible supply routing. This quad configuration enables compact, synchronized multi-channel signal conditioning without inter-channel performance degradation.
What is the power-down current consumption of THS4524MDBTREP?
In power-down mode, THS4524MDBTREP draws 20 μA typical quiescent current per enabled channel (as tested at VS = 5 V). When all four channels are disabled, total device current drops to ≤80 μA. The PDx pins are active-low with guaranteed turn-on above 2.1 V and turn-off below 0.7 V, allowing direct interface to standard logic families. Turn-on and turn-off delays are 70 ns and 60 ns respectively, supporting rapid channel gating in time-multiplexed systems. THS4524MDBTREP maintains this ultra-low standby current across the full –55°C to 125°C operating range.
Is THS4524MDBTREP pin-compatible with other devices in the THS45xx family?
No, THS4524MDBTREP is not pin-compatible with other THS45xx devices. Its TSSOP-38 (DBT) package and 38-pin layout-including 12 VS– pins, 4 PD pins, and separate VS+ per channel-are unique to the quad-channel THS4524 variant. The THS4520 (570 MHz) uses an 8-pin SOIC, and the THS4509 (dual) uses an 8-pin VSSOP. Substituting THS4524MDBTREP requires full PCB redesign due to pin count, spacing, and terminal assignment differences. Always verify mechanical and thermal constraints before migration.
