Product details
Overview
TLV9052SIDGSR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for low-voltage, high-speed signal conditioning. It delivers 5MHz unity-gain bandwidth, 15V/µs slew rate, ±0.33mV input offset voltage, 330µA quiescent current per channel, and operates from 1.8V to 6.0V supply. It is used in photodiode amplification, low-side current sensing, and sensor signal conditioning where precision, speed, and power efficiency are critical.
For engineers reviewing the TLV9052SIDGSR datasheet, TLV9052SIDGSR pinout, TLV9052SIDGSR application, or TLV9052SIDGSR equivalent, this page provides verified package mapping (VSSOP-10), confirmed shutdown functionality (dual independent SHDN pins), thermal performance data (RθJA = 170.4°C/W), capacitive-load drive capability (150pF), and design-meaningful electrical specifications including RFI/EMI filtering and no phase reversal under overdrive.
Technical Context
The TLV9052SIDGSR implements a CMOS input stage with ultra-low input bias current (2pA typ) and integrated RFI/EMI filtering, enabling robust operation in noisy industrial environments. Its unity-gain stable architecture supports direct use in gain-of-1 configurations without external compensation.
It features dual independent shutdown control (SHDN1/SHDN2), allowing selective channel disablement with 6µs turn-off and 35µs full-enable times. The open-loop output impedance is resistive (~250Ω), simplifying stability with capacitive loads up to 150pF and eliminating need for isolation resistors in many buffer applications.

Pinout & Package
TLV9052SIDGSR is housed in a 10-pin VSSOP (DGS) package measuring 3mm × 4.9mm, with exposed thermal pad connected to V– for enhanced thermal dissipation (RθJB = 113.5°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1– (Pin 2) | Inverting input, Channel 1 | Accepts differential or single-ended signals; rail-to-rail common-mode range supports direct connection to current-sense resistor outputs |
| IN1+ (Pin 3) | Noninverting input, Channel 1 | Used for reference-based amplification (e.g., thermistor bridges); low 2pA bias current minimizes resistor-divider errors |
| IN2– (Pin 8) | Inverting input, Channel 2 | Enables second independent signal path - e.g., dual-axis sensor conditioning or redundant monitoring |
| IN2+ (Pin 7) | Noninverting input, Channel 2 | Supports matched-pair configuration with Channel 1; identical input characteristics ensure channel-to-channel tracking |
| OUT1 (Pin 1) | Output, Channel 1 | Rail-to-rail swing (16mV from rails @ 5.5V/10kΩ) drives ADC inputs or analog comparators directly |
| OUT2 (Pin 9) | Output, Channel 2 | Independent output enables simultaneous signal routing without crosstalk; 115dB dc channel separation prevents interference |
| SHDN1 (Pin 5) | Shutdown control, Channel 1 | Active-high logic: <0.7V disables (IQSD <1µA), >0.9V enables; permits dynamic power gating in firmware-controlled systems |
| SHDN2 (Pin 6) | Shutdown control, Channel 2 | Independent of SHDN1 - allows asymmetric power management (e.g., keep Channel 1 active for wake-up detection while sleeping Channel 2) |
| V– (Pin 4) | Negative supply / ground | Reference node for both channels and shutdown logic; thermal pad must be soldered to PCB ground plane for thermal compliance |
| V+ (Pin 10) | Positive supply | Accepts 1.8–6.0V; internal regulation ensures consistent performance across supply variation; PSRR ≥80µV/V (135dB) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of 1.8V–6.0V supply range - maximizes dynamic range in low-voltage ADC interfaces without level-shifting |
| Internal RFI/EMI filter | Rejects high-frequency noise from switching power supplies or RF sources without external RC networks - reduces BOM count and layout sensitivity |
| No phase reversal | Guarantees predictable output polarity during input overdrive - eliminates latch-up risk in sensor fault conditions (e.g., broken thermocouple) |
| Capacitive-load drive (150pF) | Stable operation into typical ADC input capacitance or long PCB traces - avoids need for series isolation resistors in most applications |
| Low input bias current (2pA) | Minimizes voltage error across high-impedance sources (e.g., pH electrodes, photodiodes) - preserves signal integrity without guard rings |

FAQ
What is the maximum capacitive load the TLV9052SIDGSR can drive while maintaining stability?
The TLV9052SIDGSR is characterized for stable operation with up to 150pF capacitive load at unity gain, as confirmed in the datasheet's Phase Margin vs Capacitive Load plot (Figure 6-17). Its resistive open-loop output impedance simplifies stabilization beyond this point, though layout parasitics should be minimized when approaching this limit. This makes TLV9052SIDGSR suitable for driving typical 10–100pF ADC inputs without external isolation components.
Does the TLV9052SIDGSR support true rail-to-rail input common-mode range?
Yes, the TLV9052SIDGSR supports rail-to-rail input with a common-mode voltage range of (V–) – 0.1V to (V+) + 0.1V across its full 1.8V–6.0V supply range. This is explicitly specified in Section 6.3 (Recommended Operating Conditions) and validated over temperature (–40°C to +125°C). The feature enables direct interfacing with grounded shunt resistors or single-supply sensors without external level-shifting circuitry.
How does the shutdown function operate on the TLV9052SIDGSR?
The TLV9052SIDGSR features two independent shutdown pins: SHDN1 (Pin 5) and SHDN2 (Pin 6). Each is active-high - pulling below 0.7V disables the respective channel (reducing quiescent current to <1µA), while pulling above 0.9V enables it. Enable/disable timing is 35µs (full) and 6µs respectively, as measured from 50% SHDN transition to 90%/10% output level. This allows granular power management per channel in TLV9052SIDGSR-based systems.
Is the TLV9052SIDGSR susceptible to phase reversal during input overdrive?
No, the TLV9052SIDGSR is explicitly designed to prevent phase reversal under overdrive conditions, as demonstrated in Figure 6-18 ("No Phase Reversal") of the datasheet. This behavior is guaranteed across temperature and supply voltage ranges, eliminating output polarity uncertainty during sensor fault events - a critical reliability feature for safety-critical signal chains using TLV9052SIDGSR.
What is the typical input voltage noise density of the TLV9052SIDGSR at 1kHz?
The TLV9052SIDGSR has a typical input voltage noise density of 20nV/√Hz at 1kHz, as specified in Section 6.7 (Electrical Characteristics) of the datasheet. This value is measured at VS = 5V with RL = 10kΩ and is consistent across the TLV905x family. Combined with its low 15nV/√Hz broadband noise at 10kHz, this makes TLV9052SIDGSR well-suited for medium-bandwidth precision applications like strain gauge or thermopile amplification.
