Product details
Overview
TLV6742IDSGR from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for low-noise precision applications. It delivers 3.5 nV/√Hz input voltage noise, 10-MHz gain bandwidth, ±3 pA input bias current, and operates from 1.7 V to 5.5 V supply. It is used in transimpedance amplifier circuits and professional audio amplifiers where low distortion and wide dynamic range are critical.
For engineers reviewing the TLV6742IDSGR datasheet, TLV6742IDSGR pinout, TLV6742IDSGR application, or TLV6742IDSGR equivalent, this page provides verified specifications, package-validated pin functions, real-world use cases, and two confirmed alternative parts with documented technical and application differences.
Technical Context
The TLV6742IDSGR employs a unity-gain-stable CMOS input stage with integrated RFI/EMI rejection filtering and no phase reversal under overdrive. Its resistive open-loop output impedance enables stable operation into ≥20 pF capacitive loads without external compensation.
It features robust ESD protection (2-kV HBM), operates across –40°C to +125°C, and supports single-supply configurations down to 1.7 V. The device includes rail-to-rail output swing with ≤14 mV headroom at 10 kΩ load and maintains <0.00015% THD+N at 1 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Noise density | 3.5 nV/√Hz at 10 kHz - enables high-resolution signal conditioning in sensor front-ends |
| Gain bandwidth | 10 MHz - supports fast-settling closed-loop designs up to ~1 MHz at G = +10 |
| Input bias current | ±3 pA - preserves accuracy in high-impedance photodiode or piezoelectric transducer interfaces |
| Offset voltage drift | ±0.2 µV/°C - ensures <1.2 µV total drift over full –40°C to +125°C operating range |
| Supply range | 1.7 V to 5.5 V - allows direct integration with Li-ion, 1.8-V logic, and 5-V legacy systems |
| Quiescent current | 990 µA per channel - balances low power with high-speed performance for portable instrumentation |
| EMIRR | 71 dB at 2.4 GHz - suppresses RF interference in wireless-adjacent industrial and audio equipment |
Pinout & Package
TLV6742IDSGR is packaged in an 8-pin WSON (DSG) with exposed thermal pad (2.00 mm × 2.00 mm body). The thermal pad must be soldered to a PCB ground plane for optimal thermal performance and EMI immunity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of channel 1 - rail-to-rail capable, drives ≥10 kΩ load with ≤14 mV headroom |
| 2 | V– | Negative supply or ground reference - connects to PCB ground plane and thermal pad |
| 3 | IN1– | Inverting input, channel 1 - high-impedance CMOS node (10 GΩ || 6 pF) |
| 4 | IN1+ | Noninverting input, channel 1 - matched to IN1– for <1.2 mV max offset at 25°C |
| 5 | IN2+ | Noninverting input, channel 2 - electrically isolated from channel 1; 130 dB channel separation at 20 kHz |
| 6 | IN2– | Inverting input, channel 2 - shares same input structure and bias current as IN1± |
| 7 | OUT2 | Output of channel 2 - independent output stage; no crosstalk-induced settling delay |
| 8 | V+ | Positive supply - accepts 1.7–5.5 V; decoupling capacitor required within 2 mm |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 5–14 mV of rails at 10 kΩ load - maximizes dynamic range in low-voltage single-supply systems |
| Unity-gain stability | Stable at G = +1 with ≥20 pF capacitive load - eliminates need for external compensation networks |
| Integrated EMI filter | 71 dB rejection at 2.4 GHz - prevents cellular/Wi-Fi noise from modulating analog signal paths |
| No phase reversal | Remains linear during input overdrive - avoids latch-up or uncontrolled output slewing in transient conditions |
| High ESD tolerance | 2-kV HBM rating - withstands handling and board-level assembly without special precautions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2376IDGKR | Lower noise (4.2 nV/√Hz), higher IQ (760 µA/ch), no shutdown, 2.2–5.5 V supply | Lacks shutdown pins; less suitable for battery-powered TIA systems requiring power gating | Preferred when lowest possible noise dominates over power control and supply flexibility |
| LMV722MMX/NOPB | Higher noise (14 nV/√Hz), lower GBW (10 MHz), higher IQ (1.3 mA/ch), 2.7–5.5 V supply | Not rated for –40°C to +125°C; unsuitable for automotive or industrial temperature-critical designs | Acceptable only in cost-sensitive commercial applications with relaxed noise and temp requirements |
Compared with OPA2376IDGKR and LMV722MMX/NOPB, TLV6742IDSGR uniquely combines 3.5 nV/√Hz noise, 1.7-V operation, shutdown capability, and extended temperature range - making it the only option qualified for high-accuracy, low-power, wide-temp industrial sensing.

FAQ
What is the maximum capacitive load the TLV6742IDSGR can drive while remaining stable?
The TLV6742IDSGR is unity-gain stable and can drive ≥20 pF capacitive loads without external compensation. Its resistive open-loop output impedance ensures phase margin remains >55° even with 20 pF directly on the output, enabling direct connection to ADC inputs or long PCB traces without oscillation risk. This behavior is validated in Figure 7-58 of the official SBOS817I datasheet for TLV6742IDSGR.
Does the TLV6742IDSGR support true single-supply operation down to 1.7 V?
Yes, the TLV6742IDSGR supports true single-supply operation from 1.7 V to 5.5 V. At 1.7 V, it maintains rail-to-rail output swing, 10-MHz gain bandwidth, and specified input common-mode range (V– to V+ – 1.2 V). Operation between 1.7 V and 1.8 V is recommended only for ambient temperatures from 0°C to 85°C per Section 7.3 of the TLV6742IDSGR datasheet.
How does the TLV6742IDSGR's EMI rejection compare to standard op amps?
The TLV6742IDSGR achieves 71 dB electro-magnetic interference rejection ratio (EMIRR) at 2.4 GHz - significantly higher than typical general-purpose op amps (<40 dB). This is enabled by an integrated RFI/EMI rejection filter, allowing reliable operation near Wi-Fi, Bluetooth, and cellular transceivers without additional shielding or ferrite beads in the TLV6742IDSGR signal path.
What is the thermal pad connection requirement for the TLV6742IDSGR WSON package?
The exposed thermal pad on the TLV6742IDSGR DSG package must be soldered to a PCB ground plane. Per Section 8.3.8 of the datasheet, this connection is mandatory for achieving rated thermal resistance (RθJB = 44.6°C/W) and ensuring EMI immunity. Floating or unconnected thermal pads degrade both junction temperature and 2.4-GHz EMIRR performance of the TLV6742IDSGR.
Is the TLV6742IDSGR pin-compatible with other dual-channel op amps in WSON-8 packages?
No, the TLV6742IDSGR uses a proprietary WSON-8 pinout (DSG) that differs from industry-standard dual op amp layouts. Its pin 2 is V– (not IN–), and pin 4 is IN1+, not OUT2. Substituting with non-TLV674x WSON-8 op amps requires PCB redesign. Always verify pin mapping using Figure 6-3 and Table 6-2 in the TLV6742IDSGR datasheet before layout.
