Texas Instruments LMV712LD

Overview

LMV712LD from Texas Instruments is a dual rail-to-rail input/output operational amplifier with independent shutdown control per channel, designed for low-voltage portable and RF power amplifier control applications. It delivers 5 MHz gain-bandwidth, 5 V/µs slew rate, 20 nV/√Hz input voltage noise, 1.22 mA/channel supply current, and operates from 2.7 V to 5.5 V.

For engineers reviewing the LMV712LD datasheet, LMV712LD pinout, LMV712LD application, or LMV712LD equivalent, this device is selected for precision analog signal conditioning in space-constrained, battery-powered systems requiring glitch-free turn-on, capacitive load tolerance up to 200 pF, and stable operation across –40°C to 125°C.

Technical Context

The LMV712LD uses parallel NMOS and PMOS input stages to achieve rail-to-rail input operation, with internal logic dynamically allocating bias current across the common-mode range - resulting in a VOS crossover point at ~1.4 V above V−. Its output stage combines PMOS and NPN transistors for true rail-to-rail swing and low-output-impedance drive.

Independent shutdown pins (SDA, SDB) reduce each channel's supply current to <1.5 µA in shutdown mode while holding the output near V−; turnon time is 2.2 µs (typ.) at 5 V with smooth, glitch-free ramping - critical for PA bias control loops where output transients must be avoided.

Key Specifications

Pinout & Package

FAQ

What is the maximum capacitive load the LMV712LD can drive without external compensation?

The LMV712LD is specified to remain stable with up to 200 pF of capacitive load in unity-gain configuration. This capability eliminates the need for series isolation resistors in many RF detector, filter, or cable-driver applications. For loads exceeding 200 pF, TI recommends adding an isolation resistor (RISO) between the LMV712LD output and the capacitive load, as shown in Figure 32 of the LMV712-N datasheet. The LMV712LD itself does not require external compensation under the 200 pF limit.

Does the LMV712LD support true rail-to-rail input and output operation?

Yes, the LMV712LD supports rail-to-rail input operation from V− −0.3 V to V+ +0.3 V and rail-to-rail output swing within 120 mV of both supply rails (at 10 kΩ load). This is achieved through parallel NMOS/PMOS input pairs and a complementary PMOS/NPN output stage. The input stage includes internal logic to manage bias current across the full common-mode range, though users should avoid the VOS crossover region (~1.4 V above V−) in high-accuracy applications.

How does the shutdown functionality work on the LMV712LD?

The LMV712LD features two independent shutdown pins: SDA controls Channel A and SDB controls Channel B. Driving either pin below 0.8 V (typ.) places the corresponding amplifier into shutdown mode, reducing its supply current to ≤1.5 µA and pulling its output to V−. To enable the channel, the shutdown pin must be pulled high - ≥2.4 V at 2.7 V supply or ≥4.5 V at 5 V supply. The output ramps up smoothly with no glitch upon exit from shutdown, with typical turnon time of 2.2 µs at 5 V.

What is the operating temperature range for the LMV712LD?

The LMV712LD is rated for operation from –40°C to 85°C, consistent with the LMV712-N commercial-grade specification. It is not the automotive-qualified LMV712-N-Q1 variant (which extends to 125°C), nor is it rated for military or extended industrial temperature ranges. All electrical characteristics - including input offset voltage, supply current, and output swing - are ensured across this –40°C to 85°C range per the datasheet's Recommended Operating Conditions table.

Which package type corresponds to the LMV712LD part number?

The LMV712LD is the 10-pin DSBGA (Die Size Ball Grid Array) package variant of the LMV712-N family, identified by Texas Instruments' YPA package code. Its nominal body size is 1.75 mm × 2.25 mm with a 0.5 mm ball pitch. This package provides superior thermal performance and minimal PCB footprint compared to the 10-pin WSON (NGY) and 10-pin VSSOP (DGS) variants - making it ideal for ultra-compact portable and RF applications where space and thermal dissipation are critical.
